Probability of a positive qPCR Ct-value in relation to increasing Schistosoma haematobium egg counts from urine filtration microscopy. Red dots: S. haematobium egg counts in qPCR-positive (top) or qPCR-negative negative (bottom) samples, when Ct-values of < 33 are considered as positive; red and blue dots: S. haematobium egg counts and microhaematuria in qPCR-positive or qPCR-negative negative samples, when Ct-values of < 33 are considered as positive; red line: probability curve for Ct-values < 33 to become positive if urine filtration is the reference test; blue line: probability curve for Ct-values < 33 to become positive if urine filtration plus reagent strip tests are the reference test; dotted red line: probability curve for Ct-values < 34 to become positive if urine filtration is the reference test; dotted blue line: probability curve for Ct-values < 34 to become positive if urine filtration plus reagent strip tests are the reference test; dashed red line: probability curve for Ct-values < 32 to become positive if urine filtration is the reference test; dashed blue line: probability curve for Ct-values < 32 to become positive if urine filtration plus reagent strip tests are the reference test
