对于不同的疾病及治疗方法,比较的内容也不尽相同。一般而言,对肝炎、肺炎、皮肤病等急性或较轻疾病的近期疗效,主要比较试验组与对照组之间,在治愈率及病死率上的差异;而对肿瘤、结核、心肌梗塞等慢性或严重疾病的远期疗效,主要比较两组间在生存率上的差异。近期疗效和远期疗效的比较方法较多,现分别介绍序贯分析法及存活率的直接计算法。一、序贯分析(sequential analgsis) 临床治疗效果分析通常根据预先确定的病例样
The contents of comparison are different for different diseases and treatment methods. In general, the short-term efficacy of acute or less severe diseases such as hepatitis, pneumonia, and skin diseases is mainly to compare the difference in cure rate and mortality rate between the experimental group and the control group, and to tumors, tuberculosis, myocardial infarction, etc. The long-term efficacy of chronic or severe disease is mainly to compare the differences in survival rates between the two groups. There are many methods to compare the short-term efficacy and long-term efficacy. Sequential analysis and direct calculation of survival rate are introduced separately. First, sequential analgsis Clinical efficacy analysis is usually based on pre-determined cases
