GWAS, genome-wide association studies; GAIN-MDD, Genetic Association Information Network—Major Depressive Disorder; NHS, Nurses' Health Study.
Use the GWAS result from GAIN-MDD as the training set, and use each of the four NHS substudies as the testing set on recurrent composite depression score. The final weighted R2 and P-value calculated meta-analytically across four NHS substudies.
Denotes Nagelkerke's R2%.
