老师好!meta分析中有一句话没看明白,
The Yate correction was used for those studies that contained a zero in onecell for the number of events of interest in one of the two groups[16,17].These “zero cells” created problems with the computation of ratio measure and its standard error of thetreatment effect.
其中这个Yate correction 是什么东西?以上这句话怎么理解呢?
而且后文提到解决方法是,:This was resolved by adding the value “0.5” ineach cell of the 2 X 2 table for the study in question.
这又应该怎么理解?
谢谢老师!
