Egger test for publication bias
Hi all, 

I am wondering about the details of how SDM computes the Egger test. I compared the results of the SDM-implemented Egger test with the Egger test in the metafor package in R, and while the overall conclusions were the same, the t and p values were different. Does SDM use only the last imputation for a given study, or average over all imputations? What kind of model is being specified and what is the predictor of the regression (standard error, sample size, etc.)? 

Thanks very much.
