Statistical Analysis
Statistical Package for the Social Sciences (SPSS IBM Corp.; Armonk, NY, USA) version 22 software package was used to analyze the data. The independent-samples t-test, chi-square test, and Fisher’s exact test were used to compare the two groups. Quantitative data were expressed as mean ± standard deviation values in tables. Categorical data were presented as numbers (frequency) and percentages (%). Data were analyzed at a 95% confidence level, and p value was considered significant if less than 0.05.
