摘要: 目的 探讨多中心临床试验中实验室数据的定性分析方法。方法 通过计算疗前正常者疗后异常的发生率, 判断药物对实验室指标的影响;计算疗后实验室检查结果高于疗前者的比例, 检验试验结果的随机性。结果 多中心临床试验中实验室定性资料的分析可以抵消年龄、性别、中心间差异的影响, 为判定药物的安全性提供重要线索。结论 多中心临床试验中实验室资料既要进行定性分析, 又要进行定量分析。

Abstract: AIM: To study the qualitative methods for analyzing laboratory variables from multi-center clinical trial.METHODS: Two methods were proposed.One is to compare the proportions of persons whose values are clinical abnormal after treatment but normal before treatment.The other is to test the randomness of the difference of the values before and after treatment.RESULTS: Both of the methods can eliminate the difference between centers , as well as the difference between age groups and gender.The likelihood ratio test or Fisher's exact probability method should be used for first method , and u test or exact method based on binomial distribution with rate 0.5 for second method.CONCLUSION: In multi-center clinical trial , both qualitative and quantitative methods should be used for laboratory variables to evaluate the safety and tolerability of the drug being tested.

Key words: multi-center clinical trial, laboratory data, qualitative analysis, likelihood ratio test, exact method
