Fig. 1From: The impact of community-wide, mass drug administration on aggregation of soil-transmitted helminth infection in human host populationsObserved relationship between measured prevalence and aggregation, k, from TUMIKIA project. Originally published in Truscott et al. [34]. The crosses in represent the prevalence values of 10% and 60%. In the TUMIKIA study, the lowest k-values were found in low prevalence clusters (< 10%) and the highest k-values were found in clusters with a prevalence of approximately 60%Back to article page
