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.
