  1. aPrevalence values were calculated for individual sites based on the sample of audited records, but assuming they were representative of the full site before calculating mean prevalence. As this value is an estimate, 95% confidence intervals are included. Model mean prevalence estimates are based on log-transformed prevalence values, which are then back-transformed.
