Note. Partially shaded bars indicate studies that were excluded from analysis due to demonstrating an ESsg </> 2 standard deviations from sample mean.

Plot of effect sizes (g) & 95% confidence intervals for overall cognition and specific cognitive constructs (AP, HC, Mem, PS).
Note. Values labled as “Corrected” are corrected for publication bias via an extension of Egger’s regression test [42] as defined in the Methods section above.
