Intraclass correlation coefficient (ICC) values with confidence intervals for measures of P1, N1, P2 latency and P1N1 and P2N1 peak-to-peak amplitudes for the locations bladder dome (BD) and trigone (TG). In addition, ICC values are indicated for pudendal SSEP latencies (P40, N50, P65, N85) and peak-to-peak amplitudes (40N50, P65N85).
