Statistical analysis
The Statistical package for Social Science (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp.) was used for data management and analysis. Descriptive statistics were presented as Mean, Standard deviation (± SD) or numbers and percentages. Chi-Square test was used to assess the relationship between two qualitative variables. Student T Test was used to detect the statistical significance of the difference of the parametric variable between two study group means. Fisher’s exact test was used to estimate the relationship between two qualitative variables. The P value is considered significant if < 0.05.
