Statistical Analysis
The Statistical Package for the Social Sciences (SPSS) for Windows,
version 23.0 was used for the evaluation of the data. The Shapiro-Wilk
test was used to determine the normality of distribution. Continuous
variables were expressed as median and ranges, and their statistical
analysis was performed using the Mann-Whitney U test. Categorical
variables were expressed as number and percentages and analyzed using
the chi-square test. Differences were considered statistically
significant when the p value was <0.05.
