Coming soon

The R script used to compute the meta-analytic estimates — multilevel random-effects pooling (Fisher-z, effects within samples within studies) with cluster-robust (CR2) intervals. Covers the estimation only, not the site's figures.

csdt-analysis.R

Calculated results

Coming soon

Pre-computed pair-wise meta-correlations from the current database version. Includes r, 95% CI, k, N, and I² for every pair.
