Examples

### copy data into 'dat'
dat <- dat.bcg

### calculate log risk ratios and corresponding sampling variances
dat <- escalc(measure="RR", ai=tpos, bi=tneg, ci=cpos, di=cneg, data=dat)

### fit mixed-effects meta-regression model
res <- rma(yi, vi, mods = ~ alloc + ablat, data=dat)

### test the allocation factor
sav <- anova(res, btt="alloc")
sav

### turn object into a regular data frame
as.data.frame(sav)

### test the contrast between levels random and systematic
sav <- anova(res, X=c(0,1,-1,0))
sav

### turn object into a regular data frame
as.data.frame(sav)

### fit random-effects model
res0 <- rma(yi, vi, data=dat)

### LRT comparing the two models
sav <- anova(res, res0, refit=TRUE)
sav

### turn object into a regular data frame
as.data.frame(sav)
