Note: Data: mean (standard deviation). SI: similarity of the whole sulcal pattern, SI_a: similarity between corresponding sulcal basins, SI_b: similarity of intersulcal relationship. The P-value for the regression model includes gestational age at MRI as a covariate. An FDR correction was applied for P-values. *Corrected P < 0.05 with FDR correction.
