‡Independent t-test and †Mann-Whitney U test were used to test for significance of differences between parametric and nonparametric variables, respectively. ∗Chi squared test was used to test for association between categorical variables. A p-value < 0.05 was considered significant (p values of significant variables are in bold print).
