They usually have a definition for the kinds of studies they'll use. For example, they might say "only studies of this size betwee these years that measure this thing". I'll bet if you read the full analysis, you'll find something like that in it.
- oh_sigh 12y agoYou're correct. The full study has a cool flow chart of how they selected their papers, how they removed certain studies, mixed in other studies, etc. But it doesn't handle the case of papers that were never published in the first place. I'm not even sure it's possible to handle, which is what I'm asking.
