Statistical analysis
The Kolmogorov–Smirnov test was done to investigate the normality of data. Between‐group comparisons of quantitative variables and their mean changes were made using independent samples t-test or Mann–Whitney U test for normally and non-normally distributed data, respectively. A Comparison of qualitative variables and their mean changes between the groups was done using the Chi‐square test and Fisher exact test. Within‐group comparisons were done using paired samples t-test or Wilcoxon signed‐ranks test for normally and non-normally distributed data, respectively. Results were expressed as mean ± standard deviation. All statistical analyses were assessed by Statistical Package for Social Science version 24 (SPSS Inc., Chicago, IL, USA).P-values equal or less than 0.05 were considered statistically significant.
