Table 1.

The range, mean, median and correlation coefficients of the different subject-specific correction factors

Correction factor Range Mean Median Range of r2 Mean r2
QTcC 0.28–0.55 0.41 0.39 0.74–0.98 0.92
QTcX 0.28–0.54 0.40 0.39 0.85–0.98 0.93
QTcR 0.12–0.51 0.27 0.26 0.10–0.93 0.52
QTcG 0.41

QTcC = subject-specific correction factor from combined exercise and resting day data, QTcX = a subject-specific correction method from exercise alone, QTcR = a subject-specific correction factor from resting day only and QTcG = a study-specific correction method.
