I have performed meta-analysis and included four different tests for publication bias in the analysis - classic fail-safe N, Orwin's fail-safe N, Duval and Tweedie's trim and fill as well as funnel plots. The tests did not seem to indicate publication bias in my material - according to classic fail-safe N 23 papers would be needed to bring the result to p > 0.05, according to Orwin's fail-safe N 8 papers would be needed to reduce the OR into a trivial one, trim and fill test did not show adjustments and funnel plot was symmetrical.
However, one of my reviewers wants me to include cut-offs for publication bias tests in the Methods. I have tried to look for any cut-offs that would be commonly used with these tests but in many cases even the interpretation of results is not very exact. How should I proceed with this problem, what should I answer to the reviewer?
