Data are n (%) unless otherwise specified, P values for categorical variables were estimated using χ2 tests and the Wald test in the logistic regression models.
*The combined CT/NG group represents a CPT code for either CT or NG, or both.
†Adjusted OR based on age, region, and CCI.
CI indicates confidence interval; n/a, not applicable; OR, odds ratio.
