Fig. 2From: A Suspicion Index to aid screening of early-onset Niemann-Pick disease Type C (NP-C)Performance assessment (sensitivity and specificity) plots for NP-C cases versus NP-C non-cases and controls. High sensitivity and specificity was achieved with NP-C cases versus NP-C non-cases or controls, and aided the assignment of cut-off scores (vertical dashed lines) for low (<3), moderate (3–5) and high (≥6) likelihoodBack to article page
