Figure 3

Comparison of patient LDLs to a normal-hearing reference group (12). Top panels: Cumulative LDL distributions. Black solid lines – all patients; gray solid lines – patients with normal hearing thresholds; black dashed lines – reference group. Dotted lines indicate 10 and 90% level. Bottom panels: Receiver operating characteristic curves (see Materials and Methods). Black solid lines – all patients compared to reference group; gray solid lines – patients with normal hearing thresholds compared to reference group. Dotted lines indicate 90% true positives and 10% false positives. Panels (A–D) show the data for 500, 1000, 2000, and 4000 Hz, respectively.
