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.
