Data are means ± SD and intra-class correlation coefficients (ICC); t, time moment in minutes, with t = - 40, t = -15 (for brachial flow-mediated dilation measurement) and t = 0 (for glucose) as time-points before glucose intake (i.e. fasting time-points) and t = 30, t = 60, t = 75 and t = 120 as time-points after glucose intake; ICC calculated over the fasting time-points by ANOVA; n = 22. D_base, baseline diameter; ∆D_peak, peak change in diameter; ∆D_peak/D_base is the %FMD measure; v_base, baseline flow velocity; ∆v_peak, peak change in flow velocity; ∆v_mean, mean change in flow velocity; ∆v_peak/v_base, peak change in flow velocity relative to its baseline flow velocity; ∆v_mean/v_base, mean change in flow velocity relative to its baseline flow velocity; ∆D_peak/D_base divided by ∆v_peak/v_base is pFMD_v; ∆D_peak/D_base divided by ∆v_mean/v_base is mFMD_v; pxl, pixels.
