在多中心临床药物研究的总结阶段，对各参研单位汇集的大量病例资料进行数据分析一直困扰着研究者。一般的通用统计软件只能作具体的统计学计算，每分析一个指标，就要整理一次病例数据。大批量、多类型的数据来之不易。但人工操作的工作量庞大、差错率高、复核困难,常常限制了
In the concluding phase of multi-center clinical drug research, the data analysis of a large number of case data collected by various research institutes has plagued the researchers. General general statistical software can only make specific statistical calculations, each analysis of an indicator, it is necessary to organize a case data. High-volume, multi-type data is not easy to come by. However, the manual work of the huge workload, high error rate, review difficulties, often limited
