Model 1: Adjusted for age, race, sex, and body mass index percentile. HSV and HSD were entered into separate models.
Model 2: Adjusted for age, race, sex, and body mass index percentile. HSV and HSD were included the same model to adjust for each other.
Model 2a: Model 2 + additional adjustment of total caloric intake.
Model 2b: Model 2 + additional adjustment of total fat intake.
Model 2c: Model 2 + additional adjustment of carbohydrate intake.
