Effects of OFC folding patterns (sulcogyral type and POS frequency) on symptoms and cortical thickness (for variables where folding patterns were significant for temperament dimensions).

	Folding pattern	Post hoc tests
Left type
Left orbital gyrus thickness	F(4,48) = 3.273, P = 0.047b	I < IIb
Left medial orbital sulcus thickness	F(4,48) = 3.452, P = 0.040b	I & III < IIb
Right type
Depressive symptoms	F(2,131) = 4.43, P = 0.014	I > II & III
Right gyrus rectus thickness	F(4,108) = 6.08, P = 0.003	I & II < III
Right lateral orbital sulcus thickness	F(4,108) = 3.618, P = 0.030	I < II & III
Right POS
Depressive symptoms	F(2,128) = 3.51, P = 0.033	2 > 0 & 1a

Note that only significant effects are shown for clarity; statistics for non-significant (P > 0.05) effects are available from the authors. I, II and III indicate sulcogyral pattern types I, II and III, respectively. 0, 1 and 2 indicate zero, one and two POS, respectively.

Post hoc tests are shown at P < 0.05 (^asignificant at P < 0.1).
