[R-meta] Peto random effect?

Dear r-sig-meta community,

In Revman, doesn't seems to be options to do a Peto with random effect,
But I see that is available in meta and metafor.

Am I missing something here? Does any one know the reason why is not
available in Revman?

I cannot answer the question concerning RevMan.

The Peto odds ratio (POR) for an individual study is constructed under 
the null hypothesis of no treatment difference, i.e., a true odds 
ratio of 1. This implies that the POR is a biased estimate of the OR 
for large treatment effects, i.e., if the true odds ratio is far away 
from 1 (Brockhaus et al., 2014).

One may argue that the Peto method, i.e., a meta-analysis using the 
POR as effect measure, is inherently a fixed effect / common effect 
method due to its construction under the null hypothesis of no 
treatment difference. However, in my view, the POR is an effect 
measure and I do not see why it should not be used in a random effects 
meta-analysis.

Best, Guido
