Categorical variables were expressed as number (%), continuous variables as mean (± SD). Chi-squared tests or Fisher’s exact tests were used in the case of categorical variables while t-tests or Mann–Whitney tests were used in the case of continuous variables. P < 0.05 in two-tailed tests was considered as statistically significant.
