Data analysis
The Statistical Package for the Social Sciences (SPSS) software (version 25.0, Armonk, NY: IBM Corp., USA) was used for statistical analysis. Descriptive statistics, including mean, standard deviation, frequency, and percentage were used to describe the variables. Based on the results of the Kolmogorov-Smirnov normality test, the independent t-test was used to compare continuous variables between groups. The Fisher’s exact test was used to compare categorical variables between groups. P-value ≤ 0.05 was considered statistically significant.
