OR odds ratio, CI confidence interval.
aIndicates the number and percentage of participants with different education levels.
bOR and 95% CI were estimated with a multivariate logistic regression model that were controlled for age, income status, race, and smoking status. cStatistically significant results, p value < 0.05.
