Abstract

Objectives: The purpose of this study was to provide clinical evidence to support the use of auricular blood-letting therapy (ABT) for headaches. Methods: Studies were identified by a comprehensive search of five databases. Randomized controlled trials (RCTs) that investigated the effects of the ABT for headaches were included. Two authors independently extracted the data and assessed the methodological quality of the included studies using Cochrane's risk-of-bias tool. If two or more studies reported the same outcome, a meta-analysis was performed. Meta-analysis results for dichotomous variables are expressed as risk ratios (RRs) and 95% confidence intervals (CIs). Results: A total of eight RCTs were included in this review. The total effective rate (TER) was the most commonly used outcome measurement. Among the eight RCTs, five were included in the metaanalysis. The TER was not statistically significantly different in the ABT group compared to the medication group (two studies, n=55, RR=1.24, 95% CI: 0.78 to 1.96, p=0.36, I2 =86%). However, the TER of the combined ABT and medication group was significantly different compared to the medication alone group (four studies, n=159, RR=1.23, 95% CI: 1.12 to 1.35, p<0.0001, I2 = 0%). Pain and mental health-related outcomes in the combined ABT and medication group were significantly different from the control groups. The methodological quality of the included RCTs was generally low. Conclusions: ABT combined with medication may be effective for treating headaches. However, the number of studies included was small, so the results were insufficient, and statistically significant effects were not confirmed for a single implementation of ABT. Thus, well-designed further studies based on the findings of this study are recommended.
