Models do not account for the complex sample design, and therefore results are not generalizable to the US population.
The dietary pattern score reflects adherence to the dietary pattern, with a higher score reflecting greater adherence.
Calculated using unweighted survey data adjusted for urinary creatinine, age, sex, income to poverty ratio, race/ethnicity, and NHANES subsample weights.
