  1. Z-score = standard score. The z-scores were used for calculations with the Mann–Whitney U-test. Fisher’s exact test was used to calculate dichotomous variables. P ≤ 0.05 was considered statistically significant. Values are given as mean ± standard deviation, median [interquartile range (IQR)], and number
