Following publication of the above article, the authors discovered that the p-value for group difference in sex (male/female) in Table 1 was incorrect. And the authors described unclearly whether the p-value for the sex distribution was obtained by chi-square test or Fisher’s exact test. The corrected table appears below.

The authors would like to apologize for any inconvenience caused.

Table 1.

Characteristics of the study participants

	Depression (N=32)	Healthy control (N=23)	t	p
Sex, male/female (N)	7/25	11/12		0.08^*
Age (years)	41.06±13.76	38.91±11.65	0.608	0.546
eTIV (mm³)	1431259.06±124009.99	1513135.98±131707.27	-2.354	0.022
Serum uric acid levels (mg/dL)	4.50±1.05	5.00±1.07	-1.712	0.093
HAMD total score	18.31±5.15	-
BDI total score	21.18±7.48	4.81±5.04	7.78	<0.001
BAI total score	18.96±11.20	2.44±3.22	7.06	<0.001

Data are mean±standard deviation, except for the sex distribution. The p values for age, eTIV, serum uric acid levels, HAMD, BDI, and BAI scores were obtained using the independent t test.

^* Fisher’s exact test.

BAI: Beck Anxiety Inventory, BDI: Beck Depression Inventory, eTIV: estimated total intracranial volume, HAMD: Hamilton Depression Rating Scale
