Regression correlation between brain measures and GA^{^a}

Measure	AC	EC	GC	IC	MC	CR	IP	SD	BVol
Linear r	0.98	−0.96	0.97	0.98	0.98	0.95	0.95	0.97	0.95
Poly. r	0.98	−0.97	0.98	0.98	0.98	0.96	0.96	0.97	0.96
R to fTMS	0.98	−0.97	0.98	0.98	0.98	0.95	0.96	0.98	0.94

Note:—EC indicates extrinsic curvature index; GC, Gaussian curvature L² norm; IC, intrinsic curvature index; MC, mean curvature L² norm; CR, convexity ratio; IP, isoperimetric index; SD, sulcal depth; BVol, brain volume; r (R), regression; Poly., polynomial.
↵a The first and second rows are correlation coefficients between each measure and GA in linear and polynomial regressions. The third row is the linear correlation coefficients between folding measures and total maturation score.
