Meta-analyses try to find the unknown common truth by reviewing multiple studies and their methods and weighing them accourding to their percieved (really, calculated) quality.
By combining the results of the best studies and giving us an overview of them, meta-analyses really are the best studies we have.
"In addition to providing an estimate of the unknown common truth, meta-analysis has the capacity to contrast results from different studies and identify patterns among study results, sources of disagreement among those results, or other interesting relationships that may come to light in the context of multiple studies." - https://en.wikipedia.org/wiki/Meta-analysis https://en.wikipedia.org/wiki/Meta-analysis
- gus_massa 7y agoMeta-analysis is good if you assume no publication bias. The problem is that most of the times only studies with successful result get published, and in those studies only the successful (or at least interesting) parts are published. You can use meta-analysis only in areas that have pre-registered trials, and perhaps that is too optimistic.
