Abstract

The aim was to evaluate different results from using crude incidence rate (CIR) instead of agestandardized incidence rate (AIR) when comparing groups having different age structures. After selecting a report using CIRs, AIRs and their 95% confidence intervals(CI) was calculated from the raw data. The statistically significant difference between CIR and AIR was decided based on AIR's 95% CI. Comparing with CIRs, AIRs were under-estimated. In addition, there were no statistical significance of annual trends(P=0.59). These findings are an additional evidence using AIR when comparing level of occurring infectious diseases on groups with different age structures.
