Multilevel multivariable random effects logistic regression analysis of factors independently associated with active trachomaa.

aActive trachoma defined as TF (inflammatory trachoma-follicular) and/or TI (inflammatory trachoma-intense) using the WHO simplified scoring system [23].bModel 1 shows the association of predictor variables with active trachoma.cModel 2 includes the presence of C. trachomatis infection and demonstrates the effect of its inclusion on the predictor variables. Some of the association in Model 1 is mediated by C. trachomatis infection.dAdjusted Odds Ratio (aOR) using multivariable two-level mixed effects logistic regression modelling; CI = confidence interval.ep-value for Wald test (Wald's Chi2); significant associations (where p≤0.05) are highlighted in bold.
