aCE, cluster estimates obtained from age-adjusted mixed effects regression models for active trachoma and Ct (C. trachomatis) infection at baseline and follow-up. 95% CI (confidence intervals) of the SE (standard error) are quoted. Mixed effects models including all three cluster levels showed household to have the strongest effect. All cluster estimates were significant at the 1% level (Wald Chi2)
