Sohn, Kwon, Lee, Oh, Kim, Lee, Lee, and Kim: Effects of Uric Acid on the Alterations of White Matter Connectivity in Patients with Major Depression
Psychiatry Investig 2018;15(6):593-601
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
