Statistical Analysis
The obtained data were entered into SPSS software (Statistical Package
for the Social Sciences) version 24. First, they were summarized using
methods based on descriptive statistics, including the mean ± standard
deviation for quantitative variables (such as age) and frequency tables
for qualitative variables, and then to compare the groups in terms of
background variables, using the t-test, Chi-square and finally logistic
regression were analyzed. P-value less than 0.05 was considered
significant.
