临床疗效观察与评价前面所介绍的统计学方法都是用于临床近期疗效观察,一般说是住院病人或是在门诊观察室病人,而象肿瘤及慢性病其疗效的判定往往靠出院后随访观察,根据随访记录积累的材料称之为随访资料,常常需要使用特殊的统计方法——生存分析(Survival Analysis)以便进行分析。肿瘤及慢性病人常使用生存率以评价其疗 Clinical efficacy observation and evaluation The statistical methods described above are used for the clinical observation of short-term efficacy, generally referred to as inpatients or patients in outpatient observation rooms, and the determination of the efficacy of tumors and chronic diseases is often based on post-discharge follow-up observations.
