Table 5. Mean and range of the district-level intra-cluster correlation coefficient (ICC) for schistosomiasis prevalence in Malawi, Côte d’Ivoire and Liberia, as estimated from empirical mapping survey datasets.
N indicates the number of endemic mapping units (usually districts) included in the calculation.
