This study used a parametric bootstrap model to estimate intracluster correlation coefficient (ICC) for trachomatous inflammation-follicular (TF) in 1-9 year-olds, from 261 population-based trachoma prevalence surveys completed using standardised GTMP methodologies in Ethiopia, Mozambique, and Nigeria from 2012-2016.

Results from this study were used to draw up the most recent WHO 2018 recommendations on design effect (DE) estimates for sample size calculations for survey
