Dear Dave Sackett / the list I appreciate Dave Sackett's point about inconclusive (under powered) studies and his decision to reject them for a journal like EBM - the single study here is uninformative and therefore not useful. I wonder wether he (or anyone else who edits a journal) might want to comment further on what he feels should be the fate of such studies. I for one struggle with the idea of power as a quality issue in an era when meta-analysis appears to offer the possibility of making all those small studies useful!
