Dear Brendan,

Using the 'regression method' approach could also be regarded as a form of sensitivity analysis, when focusing on the model intercept as an estimate of the 'adjusted' effect (as in the PET/PEESE methods). In fact, if I recall the findings from various simulation studies, this seems to work better than the trim and fill method.

One can also aggregate the estimates to the study level (or to whatever level needed so that the resulting aggregated values can be assumed to be independent) and then run methods that assume independence on these aggregated data (including trim and fill).

Another recent method by James Pustejovsky: https://www.jepusto.com/talk/stanford-qsu-2022-selective-reporting/
