Statistical Analysis
At the end of the study, the collected data were analyzed through SPSS (Statistical Package for Social Studies) Version 25.0 and the online Graph Pad for Windows (Prism 7). Clear values for various outcomes were determined before running frequency tests. Pearson’s chi-square test was used to evaluate differences between groups for categorized variables.
Unpaired ‘t’ test and ANOVA test were used to calculate the difference of means of quantitative variables. All tests were performed at a 5% level of significance. Thus an association was significant if the p-value less than 0.05.
