The major depressive disorder subtypes were strongly and significantly genetically correlated (rg = 0.9–0.94, prg = 0 < 8.3×10−4). These correlations did not differ significantly from 1 (all prg = 1 > 0.3), nor from each other (all pΔrg = 0 > 0.5, Figure 2, Supplementary Table 8). BD1 and SAB were strongly correlated (rg = 0.77, prg = 0 = 6×10−13, prg = 1 = 0.03), as were BD1 and BD2 (rg = 0.86, prg = 0 = 3×10−16, prg = 1 = 0.2). However, BD2 was not significantly correlated with SAB (rg = 0.22, prg = 0 = 0.02).
