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

Age (years) 41.06±13.76 38.91±11.65 0.608 0.546

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 -

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
