[R] differences between meat and metafor packages

[greg holly]

Hi all;

I have got different results (CI and Q value for heterogeneity, tau) on the
same data when I run meta and metafor for hazard ratio with a random
effects model. The basic programs for both are given below. What can cause?

Regards,
Greg

Metafor
 res <- rma(HR, SE, data=a)
predict(res, transf=exp)

Meta
 metagen(HR, SE, sm="HR", data=a)
