Fig. 2From: Combining different diagnostic studies of lymphatic filariasis for risk mapping in Papua New Guinea: a predictive model from microfilaraemia and antigenaemia prevalence surveysRelationship between antigen and Mf prevalence predicted by models A1 (pre-MDA) and A4 (post-MDA). These combined models result in a “diverging” predictive relationship between diagnostic tests as Mf prevalence increasesBack to article page
