发帖数: 523 | 1 我现在做一个retrospective trial，在数据分析上有几个问题想向各位请教。
我有两个arm比较，几个baseline characteristics有significant difference，想要
adjust baseline，但是这几个baseline和outcome之间不一定是linear的关系，在这种
情况下怎么做呢。还有就是有什么好的软件或者工具可以给初学者使用。我现在就只是
在用excel。多谢多谢。 | w*******n

发帖数: 1350 | 4 Not necessarily matching. Could be propensity score weighting (IPTW). Often
times weighting is better than matching, because (1) by matching, you are
gonna lose quite a lot subjects, and (2) with the matched data, you have to
take into account its paired nature when conducting analysis, such as using
paired t-test or McNemar test, and sometimes it would be hard to perform
such analysis, for example it's hard to find a counterpart of mixed model
under the paired nature of the matched data.
