SD, standard deviation.
Controls and cases matched at a rate of 4 controls to 1 case based on 5 criteria: NHANES release, sex, race/ethnicity, five-year age category, and BMI category.
Tested by Student t test for difference in mean or χ2 test of differences in proportion.
Total categorical values may not sum to 100% because of missing data and rounding.
