Statistical Analysis
The data was statistically analyzed by Statistical Package for the Social Sciences (SPSS) software version 21.0. The numerical data were presented as percentages or mean ± standard deviation (SD) and categorical variables as frequencies or rates where ever needed. ANOVA/Kruskal Wallis test was used for the comparison of more than two groups and the Chi-Square test for a comparison of qualitative variables. A p-value of <0.05 was considered statistically significant.
