*
The reported odds ratios (95% CIs) were calculated in comparison with whites by logistic regression adjusting for age, gender, and insurance.
†
Regression coefficients for all numeric variables in different races were calculated in comparison with whites by linear regression adjusting for age, gender, and insurance.
‡
Duration of follow-up was calculated by subtracting the age at the first visit from the age at the last visit.
