Data obtained from the three groups were compared using the Kruskal–Wallis test (†) and Dunn’s test (*). †Significant differences (p < 0.05) according to the Kruskal–Wallis test. *:significant (p < 0.05) differences according to Dunn’s test are indicated by an asterisk. The ages of the three groups were compared: Group 0 vs. Group 1(p = 0.028*), Group 0 vs. Group 2 (p = 0.009*), Group 1 vs. Group 2 (p = 0.635), and Group 0 vs. Group 1vs. Group 2 (p = 0.005). Blood pressure was also compared between Group 0 and Group 1(p = 1*), Group 0 vs. Group 2 (p = 0.002*), Group 1 vs. Group 2 (p < 0.001*), and Group 0 vs. Group 1vs.Group 2 (p < 0.001†).
