^aOR, odds ratio. Numbers in parentheses after odds ratios represent the 95% CI. NA, not applicable to gender.

^bOnly those variables that remained significant after adjustment for other variables in the model are included.

^cLack of data for the crude odds ratio is due to the low prevalence of the variable.

^dNSU, nonspecific urethritis; NSC, nonspecific cervicitis.
