R语言 制作网状META 出现的问题求助
##热图netheat map，衡量consistency
nh<-read.xlsx("smoking-netheat.xls", sheetIndex=1, header=TRUE)
nh
netre1 <- netmeta(X_y, X_stderr, X_t1, X_t2, study, data=nh, sm="MD", reference="A", comb.random=TRUE)
netre1
出现以下说法请求各位老师！！！
Error: Problems in multi-arm studies!
- Studies with inconsistent treatment estimates: '1', '13', '16', '18', '20', '21', '23', '9'
- Studies with inconsistent variances: '1', '13', '16', '18', '20', '21', '9'
- Studies with negative treatment arm variance: '1', '13', '16', '18', '20', '21', '23'
- Please check original data used as input to netmeta().
- For more details, re-run netmeta() with argument details.chkmultiarm=TRUE.
- Argument tol.multiarm in netmeta() can be used to relax consistency
assumption for multi-arm studies (if appropriate).
In addition: Warning message:
Note, treatments within a comparison have been re-sorted in increasing order.
