Figure 1From: Accuracy of malaria rapid diagnostic tests in community studies and their impact on treatment of malaria in an area with declining malaria burden in north-eastern TanzaniaOverall sensitivity of RDTs by parasite density for blood smear positive samples in the longitudinal study and CSS in Korogwe and Muheza districts. Bars represent proportion of cases with positive blood smear results by different categories of parasite density, asexual parasites/μl (black bars = longitudinal study, n = 3793; and grey bars = CSS, n = 1045); Solid line = sensitivity of RDTs in the longitudinal study and dotted line = sensitivity of RDTs in the cross-sectional surveys (CSS)Back to article page
