Some of the values in Table 6 of the published paper have been modified. The OR and 95% CI in the Female row, Model 1 column are replaced from 1.16, 1.12~1.20 to 0.73, 0.69~0.78. The OR and 95% CI in the Intercept row, Model 1 column are replaced from 0.03, 0.39~0.50 to 0.02, 0.01~0.03 (indicated in bold).

The revised Table is below.
