Associations between PNMS and genotypes with HCV/TIV ratios in boys and girls.

	Boys		Girls
	Left HCV/TIV ratio	Right HCV/TIV ratio	Left HCV/TIV ratio	Right HCV/TIV ratio
Objective PNMS	r = 0.324#	r = 0.280	r = 0.305	r = 0.392*
Subjective PNMS	r = −0.014	r = 0.317	r = 0.142	r = 0.023
Cognitive appraisal	r = −0.093	r = 0.032	r = 0.103	r = −0.019
COMT (rs4680)	r = 0.561**	r = 0.334#	r = −0.099	r = −0.259
BDNF (rs6265)	r = 0.369#	r = 0.160	r = −0.457*	r = −0.348#

HCV, hippocampal volume; TIV, total intracranial volume.

r, Pearson’s correlation coefficient; ^#p < 0.10, *p < 0.05, **p < 0.01.

Genotype coding:

COMT: AA = 1, AG = 2, GG = 3.

BDNF: CC = 1, TC = 2.
