  • Objective: This study evaluated and compared the adherence to the CONSORT for quality of reports on the randomized controlled trials (RCT) abstracts by four major Korean Science Citation Index (SCI) journals and The New England Journal of Medicine (NEJM). Methods: A descriptive analysis of published RCT abstracts in Korean SCI journals and NEJM from 2007/01 to 2011/06 was conducted by two reviewers, independently extracting data from a PubMed search. A modification of CONSORT for abstract was used including 16 checklist items. Reporting of checklist items for individual group was conducted to compare adherence patterns between two groups. Results: We identified the potential 57 RCT abstracts from Korean SCI and 50 from NEJM meeting our inclusion criteria; among them, three abstracts from Korean SCI and one from NEJM were excluded. Among total 16 checklist items based on CONSORT statement, Korean SCI journals and NEJM were statistically equivalent in 4 items; Korean journals were better in three items and NEJM were in nine. The methodological quality domains were inadequately reported in both journals: allocation concealment about 1.9% and 4.0%, and blinding 44.4% and 40.8%. In general, The CONSORT adherence of NEJM was better than that of Korean SCI in the method and result domain (p < 0.0001). Conclusions: The quality of NEJM reporting of RCT abstracts was better than that of Korean SCI, in general. This study on adherence of RCT reports from Korean SCI journals and NEJM abstracts to the CONSORT statement reveals that there is a need for improvement, especially Korean SCI. Further investigation on the quality of RCT reports and ways to improve reporting quality is required.

  • Early identification and intervention for autism spectrum disorder (ASD) were reported to be important for outcomes or clinical courses. However, there have been a few robust evidences for effectiveness of early intervention until now. This review aims to identify the effectiveness of early intervention by investigating the randomized controlled trial (RCT) of early intervention for autism. There are some RCT studies using behavioral program. Although there are some significant findings, the outcome measurements and small sample size are the limitations. Further studies are needed.

  • 서론 : 본 연구는 무작위 대조군 실험(Randomized control trial: 이하 RCT) 연구에서 치료의향분석(Intention-to-treat analysis)의 올바른 활용에 대해서 고찰하고자 한다. 본론 : 치료의향분석은 RCT 연구에서 무작위 분배 이후에 모든 대상자의 데이터를 결과에 포함하는 분석방법이다. RCT 연구의 결과는 일반화에 있어서 매우 높은 타당성을 갖는다. 이런 측면에서 중도 탈락을 포함한 모든 대상자의 데이터를 결과 분석에 포함하여야 그 결과를 실제 임상에 적용했을 때 중재의 효과가 예측 가능하기 때문이다. 이런 이유로 RCT 연구에 대한 질평가 도구들은 치료의향분석 실시여부를 확인하고 있다. 그럼에도 많은 연구자들은 치료의향분석의 이해도가 낮아 잘못 활용하고 있거나 활용하지 않는 경우가 많다. 결론 : 본 고찰 연구를 통해 국내 많은 연구자들이 치료의향분석방법을 정확하게 이해하고 올바르게 활용하여 RCT 연구에 반영할 것을 기대한다.

  • 본 연구는 2000년 1월부터 2010년 3월까지 Pubmed에 게재된 논문 중, alternative medicine 으로 검색하여 근거중심 대체의학에 대한 연구 현황을 알아보고자 문헌고찰을 하였다. 682편의 연구 중 대체의학에 관한 임상연구는 19개였으며 연구전체 대상자는 2,573명이었다. 논문분석 결과 RCT(Randomized Controlled Trial) 실험 설계연구가 44%였으며 CCT(Controlled Clinical Trials)가 16%, OD(efficacy studies with either a controlled or an Other than controlled Design) 40%였다. 가장 많은 임상실험이 시행된 중재 방법은 Acupuncture과 Massage 였다. 대상 질병군 분포는 근골격계 및 결합조직의 질환과 관련된 '통증 완화'에 대한 임상연구가 20%, 다음으로 특정 감염성 및 기생충성 질환, 신생물이 각각 15% 순이었다. 근거중심 대체의학 현황을 파악하고자 문헌 고찰한 결과 대체의학을 통한 중재가 질병치료에 효과가 있는지에 대한 과학적 근거를 제시한 임상연구가 부족하다. 대체의학의 품질, 안정성, 유효성 확보를 위해 대체의학에 대한 질 높은 연구필요하며 근거중심 대체의학의 활성화가 필요할 것으로 생각된다.

  • A total of 1,235 studies were retrieved on June 23, 2019, from 3 databases. Selected 59 studies were evaluated by year of publication, study type, subject condition/disease, acupoint, standards for reporting interventions in clinical trials of moxibustion (STRICTOM), Cochrane risk of bias (RoB), and risk of bias assessment tool for non-randomized study (RoBANS). Most studies were conducted in 2011, after which the number of studies decreased. The most common study type was 25 case reports (CR), 16 uncontrolled clinical trials (UCT), 11 randomized controlled trials (RCT), and 7 controlled clinical trials (CCT). Moxibustion treatment was mainly used for musculoskeletal and circulatory diseases/conditions. A total of 83 acupoints were used, A-shi points being the most used. As for STRICTOM, an average of 7.4 items were satisfactory for UCT and CR without a control group, and an average of 9.4 items were satisfactory for RCT and CCT. RCT was assessed using the RoB, and many items were rated as uncertain. In this study, the need for RCT of moxibustion treatment in Korea was identified. The detailed description of study methods and results will provide evidence for the efficacy of moxibustion treatment in preventive and therapeutic aspects of Korean traditional medicine.

  • Objective: By assessing the quality of methodology and synthesis of results of RCTs (Randomized Controlled Clinical Trials) with herbal acupuncture (pharmacopuncture), we hope to help with administrating herbal acupuncture therapy in clinic and conducting RCT with herbal acupuncture. Methods: Reports of RCT conducted in Korea published in medical journals until February 2009 were collected. We surveyed elementary information of RCTs, evaluated randomization, double-blinding, allocation concealment and put together the results of RCTs by seven clinical topics. Results: 38 RCTs with herbal acupuncture were selected, then adequate methods for randomization and allocation concealment were found in 39% and 5% of studies. Complete double-blinding and a clear accounting of all participants were conducted in 42% and 50% of reports. The synthesis of RCTs revealed that herbal acupuncture was useful and effective on degenerative gonarthritis, omarthralgia on cerebrovascular accident, acute ankle sprain, back sprain, neck sprain, headache, rheumatoid arthritis and tennis elbow, generally. Conclusions: Although further improvement in quality of methodology of RCTs with herbal acupuncture is required, clinical usefulness of herbal acupuncture was shown especially on disorders of musculoskeletal system via RCTs.

  • Objectives: Through using of the strong research method like a Randomized Controlled Trial: RCT, we have to heighten quality of Medical Education study. I'd like to introduce "CONSORT", which stands for Consolidated Standards of Reporting Trials. Contents: Preventive Service Task Force(200l) in USA proposed Levels of evidence for enlarging evidence-based Practice: EBP. And the CONSORT was introduced, which encompasses various initiatives developed by the CONSORT Group to alleviate the problems arising from inadequate reporting of randomized controlled trials (RCTs). the CONSORT has 13 guides like these: 1. How participants were allocated to interventions 2. Scientific background and explanation of rationale 3. Eligibility criteria for participants. The settings and locations where the data were collected. 4. Precise details of the interventions intended for each group and how and when they were actually administered 5. Specific objectives and hypotheses 6. Clearly defined primary and secondary outcome measures, When applicable. any methods to enhance the quality of measurements (e.g., multiple observations, training of assessors) 7. How sample size was determined. When applicable, explanation of any interim analyses and stopping rules 8. Method used to generate the random allocation sequence, Details of any restriction [of randomization] 9. Method used to implement the random allocation sequence 10. Who generated the allocation sequence, who enrolled participants. and who assigned participants to their groups 11. Whether or not participants, those administering the interventions, and those assessing the outcomes were blinded to group assignment. If done, how the success of blinding was evaluated 12. Statistical methods used to compare groups for primary outcome(s), Methods for additional analyses, such as subgroup analyses and adjusted analyses 13. Flow of participants through each stage (a diagram is strongly recommended) Specifically, for each group report the numbers of participants randomly assigned. receiving intended treatment, completing the study protocol. and analyzed for the primary outcome. Results and Conclusion: Randomized Controlled Trial: RCT guided of CONSORT will contribute to do stronger evidence-based medical studies.

  • Objectives : The purpose of this study is to review RCTs on pharmacopuncture treatment for musculoskeletal diseases and to establish standards of pharmacopuncture treatment model. Methods : We searched articles up to date of March 2009 via computerized databases of Pubmed, The Journal of Korean Acupuncture & Moxibustion, Journal of Korean institute of Herbal Acupuncture, Journal of Oriental Rehabilitation and Journal of Korean Oriental Medicine. Only Randomized Controlled Trials (RCT) concerning the effects of pharmacopuncture on musculoskeletal diseases. The pharmacopuncture treatment methods were assessed based on STRICTA and items considering the feature of pharmacopuncture. And the methodological quality of the trials was assessed by FEAS and modified Jadad score. Results : Eighteen trials of pharmacopuncture on musculoskeletal diseases were analyzed. Except for 4 trials comparing the effect of SBV and BV, positive outcome was reported in ten trials. Among eighteen trials; most of the trials were about Bee Venom acupuncture, and most of the trials used about five acupuncture points, mainly local acupuncture points. But, the amount of injection to each point and total injection were various. And most of trials were lack in the information about method of stimulation. The adjusted FEAS score ranged from 0 to 12, and modified Jadad scoreranged from 1 to 5. Conclusions: To standardize pharmacopuncture treatment, we need more well-designed, high quality clinical trials. And methodological assessment tools designed for pharmacopuncture treatment are also needed.

  • Objectives : To discuss the types of control groups in randomized controlled trials (RCTs) of herbal medicine, and to provide suggestions for improving the design of control group in future clinical trials. Methods : We reviewed the 8 articles about clinical trial design of Chinese herbal preparation which were published from 2005 through 2008. We selected those articles from CNKI(中國知識基礎施設工程(http://www.cnki.net)). Results : It is necessary to have control group in randomized controlled trials(RCTs) of Korean herbal preparation. But there are problems in the selection of appropriate control group drug. This paper lists several problems about the choice of control drug and puts forward some proposals and countermeasures. There are problems such as ethics and manufacturing matching placebo and positive control herbal drug. Conclusion : To improve the quality of control group design, we introduce standard drug plus placebo drug method and add-on research for placebo control group design, double dummy technique, using negative control drug or composite control drug for active control group design.
