Variability independent of the mean (VIM; a), maximum–minimum difference (MMD; b) and average real variability (ARV; c) by quartiles of the distribution of the mean systolic blood pressure (SBP) for 24-h (□), home (○) or beat-to-beat (Δ) measurements. P-values represent the linear trends across the quartiles of SBP. Reproduced from Wei et al.39
