Association between clinical signs of trachoma and ocular chlamydial infection after mass azithromycin treatments.

TF = follicular trachomatous inflammation; TI = intense trachomatous inflammation; RNA = chlamydial rRNA; DNA = chlamydial DNA.*Multivariate mixed effects logistic regression with either chlamydial RNA or DNA as the outcome, and community as a random effect.†Clinical signs of trachoma treated as a single categorical variable, with the absence of TF or TI (i.e., normal exam) as the reference; Wald p-value for categorical variable ‡Clinical signs of trachoma treated as separate dichotomous variables.
