[R-meta] Meta package - add PI to each subgroup in a forest plot

[Jorge Teixeira]

Dear all,

Is it possible to add a Prediction interval to each subgroup in a forest
plot?

I wish to display PI for each level of  "BP_threshold", instead of only an
overall PI.

I tried this with no luck.


#1
DBP <- metacont(en, em, esd, cn, cm, csd, Study, method.tau = "DL",
prediction = TRUE, comb.random = TRUE, data = dat, sm = "MD")

#2
forest_dbp_bp  <-update(DBP, byvar=BP_threshold )

#3
forest(forest_dbp_bp,    prediction = TRUE)

Thank you.
