Fig. 3From: The increased sensitivity of qPCR in comparison to Kato-Katz is required for the accurate assessment of the prevalence of soil-transmitted helminth infection in settings that have received multiple rounds of mass drug administrationScatterplot of Ascaris lumbricoides (left), Trichuris trichiura (centre) and hookworm (right) eggs per gram (EPG) of faeces results against mean DNA quantity results on log axes. EPG results were derived from the Kato-Katz (KK) technique. Mean DNA quantity results were derived from qPCR. Point colour denotes egg count infection intensity grouping as defined by the WHO [37].
