Determination of α. The solid line and the dashed area indicate the correlation coefficients between AI rd and cfPWV with the change of α. The solid line is the mean in all 12 trials and the dashed area the confidence band. The best-fit α was determined by the peak of the correlation coefficient curve in each trial. The vertical dash line indicates the mean of the best-fit α in 12 trials, and the bar indicates the standard deviation.
