- When authors from articles to be included in a meta-analysis are willing to provide patient-level data.
- Trialists or study principal investigators willing to share raw study to be combined into a single database.
- Individual participant meta-analysis combines individual participant data from multiple studies (trials, registries, etc). Since the data are much more granular than simply bringing together results extracted from publications. This granularity and the possibility of running patient-level models make individual patient meta-analysis one of the top designs in the evidence-based pyramid.

- PRISMA [1] and PRISMA extension for individual participant data [2].
