本文报告了医院与普通人群甲、乙型病毒性肝炎病例对照研究中同时使用普通对照与易感者对照进行平行研究的初步结果.医院中甲肝(病例60例,普通对照200例,易感者对照37例)乙肝(病例64例,普通对照200例,易感者对照65例)主要发病因素,人群中甲肝(普通对照时1∶3配比37对,易感者对照时1∶1配比11对)爆发因素,用两种对照方式获得的OR值均无显著差异;除个别因素外,分析效果基本一致.本文对此及其有关因素进行了讨论,初步提示在病毒性肝炎病例对照研究中使用普通对照与易感者对照都是可以的.
This article reports the initial results of a parallel study of both control and susceptible controls in both hospital and general population with case-control studies of type A and B. In hospital, hepatitis A (60 cases, 200 controls, susceptible Control 37 cases) Hepatitis B (64 cases, 200 cases of normal control, 65 cases of susceptible control) The main risk factors, the crowd of hepatitis A (1: 3 ratio of 37 normal controls, 1: 1 susceptible controls Compared with 11 pairs of) outbreak factors, the two control methods to obtain OR values were no significant differences in addition to a few factors, the analysis of the results are basically the same.This article and its related factors were discussed, preliminary tips in the case of viral hepatitis control It is possible to use both normal controls and susceptible controls in the study.
