Factors associated with chlamydial infection or active trachoma after mass azithromycin distributions—univariate analyses.

CT = Chlamydia trachomatis, as detected by AMPLICOR; TF = follicular trachoma; TI = intense inflammatory trachoma; RNA = chlamydial rRNA; DNA = chlamydial DNA.*Univariate mixed effects logistic regression with either chlamydial RNA, chlamydial DNA, or clinically active trachoma (TF/TI) as the outcome, and community as a random effect. Variables summarized as means were analyzed as continuous variables. Odds ratios with p†Penalized maximum likelihood regression using Firth's method; used because the risk factor was present in all DNA+ cases.
