Notes: Values for continuous variables given as means ± standard deviation and compared by Student’s t-test; variables not normally distributed given as medians and interquartile range and compared by Mann–Whitney U-test; values are presented as number (%), and analysis was performed using the chi-square test. *P < 0.05 was considered statistically significant.
