Means with the standard deviations (SDs) are presented for the continuous variable, and numbers with the percentages of students are presented for categorical variables. The p-values for continuous variables, such as age, are analyzed using two-sample t-test, and the p-values for categorical variables are analyzed with the Chi square test or Fisher’s exact test. A value of p < 0.05 denotes statistical significance.
