  1. Definition of abbreviations: R5: Resistance at 5 Hz; R20(19): Resistance at 20/19 Hz; R5-R20(19): Resistance at 5 minus 20(19) Hz; AX: Area of Reactance; X5: Reactance at 5 Hz; X20(19): Reactance at 20(19) Hz. p-values obtained from Wilcoxon signed rank test (paired test), 95% confidence intervals are for the median of the difference.
