Statistical Analysis
Data were collected and entered into the software of Statistical Package for Social Science (SPSS) 20. Numbers and percentage values were given to show descriptive qualitative data while mean scores, standard deviations, ranges, and medians with interquartile ranges (IQR) were given to show descriptive quantitative data. Chi-square test was used to compare the groups related to qualitative data, while the two groups were compared in terms of quantitative data and parametric distribution by using independent t-test and in terms of the nonparametric distribution by using the Mann–Whitney test. The value of P<0.05 was considered statistically significant.
