Parametric and nonparametric sampling distributions are shown as mean ± SD or median (25% - 75%) respectively. Parametric data was analysed by 1-way ANOVA with post hoc analysis (Bonferroni t-tests method) and nonparametric data by Kruskal–Wallis ANOVA on Ranks with post hoc analysis (Dunn’s method). The single number in parentheses represents the number of observations if different from the stated n in Table 1.

BV, blood volume; PV, plasma volume; LVM, left ventricular mass; LVMI, left ventricular mass index; LVEDV, left ventricular end-diastolic volume; LVEDVI, left ventricular end-diastolic volume index.
