我想从森林图中省略一些具有巨大标准误差的研究,因为它们难以解释。但我不想改变估计。下面是一个玩具示例:
### load BCG vaccine data
data(dat.bcg)
### meta-analysis of the log relative risks using a random-effects model
res <- rma(measure="RR", ai=tpos, bi=tneg, ci=cpos, di=cneg, data=dat.bcg,
slab=paste(author, year, sep=", "))
### Let's say I want to omit the first study, the rows argument doesn't work as expected
forest(res, rows = c(2:13))
Error in forest.rma(res, rows = c(2:13)) :
Number of outcomes does not correspond to the length of the 'rows' argument.
有任何想法吗?
