a If the number of people for one item is not equal to the total number, people are missing for this item, and thus, the effective percentage is presented. Continuous variable: the p value is obtained by analysis of variance (ANOVA) and linear regression; categorical variable: the p value is obtained by the two-tailed chi-square test.
