Hearing loss vs nerve conduction studies in XP-A and XP-D. The right ear 4F-PTA, defined as the four frequency (0.5/1/2/4-kHz) pure tone average, was plotted against the amplitudes of the following: A Sural sensory nerve, B Median sensory nerve, C Fibular motor nerve, D Median motor nerve. ANCOVA was used to study the interaction between complementation group and hearing level. Normal hearing: 4F-PTA ≤ 20 dB HL. Normal NCS findings: sural sensory ≥6 μV, median sensory ≥15 μV, fibular motor ≥2.5 mV, median motor ≥4.5 mV
