rmeta: forest plot problem
...de below I
plot the forest plot:
library(rmeta)
data (catheter)
a<-meta.MH (n.trt, n.ctrl, col.trt, col.ctrl, data=catheter, names=Name,
subset=c(13,6,5,3,7,12,4,11,1,8,10,2))
summary(a) # odds ratio values and confidence intervals
metaplot(a$logOR, a$selogOR, nn=a$selogOR^-2,a$names, summn=a$logMH,
sumse=a$selogMH, sumnn=a$selogMH^-2, logeffect=TRUE)
Now I would like to add numerical odds ratio values and corresponding
confidence intervals for each study on the second y axis (eg.

questions about meta-analysis
Dear R users:
In the example of meta-analysis (cochrane, package rmeta), I can not found the p-value of Test for overall effect, and some other indices (Z, I, weight and et al). How can I get the these indices listed?
