  1. Age, systolic blood pressure, and diastolic blood pressure are expressed as mean (SD), using one-factor analysis of variance (ANOVA); SuNa, Suk, Suk, and SuCr are expressed as the median (M) and interquartile range (IQR), which is used for data with non-normal distributions using Kruskal–Wallis test to compare
