Statistics
To describe the sample, descriptive statistics were used. Study parameters were assessed for normal distribution and reported as numbers (percentages) and means (SDs). Study parameters were assessed for normality by using Shapiro–Wilk test which indicated normal distribution. Continuous variables were compared using ANOVA and Bonferroni post hoc test as appropriate. Categorical variables were compared using Chi-square test or Fisher’s-exact test as appropriate. A two-tailed p-value of < 0.05 was considered to be statistically significant. Statistical analysis was conducted using SPSS 24.0 (Statistics Package for Social Sciences, Chicago, IL, USA).
