Meta-analytic estimates from MetaSDT
The estimates below are pre-computed from MetaSDT. Each correlation is a random-effects multilevel pooled estimate (Fisher-z, effects nested in samples nested in studies). For pairs with at least 30 studies, cluster-robust (CR2) intervals are reported. Data updates will be accompanied by a new version number.
When citing a specific number, please record the database version with the following citation.
