Associations between 10% increments in consumption of baseline dietary intake measures and metabolic syndrome at Year 3

	Uncalibrated			Calibrated
Dietary intake, modeled as 10% increments in:	Metabolic syndrome, n = 429
	OR1	95% CI	P value	OR1	95% CI	P value
Energy, kcal/d	0.99	0.96–1.01	0.466	1.37	1.15–1.63	<0.001
Total protein, g/d	0.99	0.96–1.01	0.659	1.21	1.00–1.47	0.053
Protein density, % energy from protein2	1.02	0.94–1.10	0.698	1.02	0.77–1.35	0.880
Animal protein, g/d3	1.00	0.97–1.03	0.962	1.08	1.02–1.14	0.006
Vegetable protein, g/d3	0.98	0.94–1.01	0.201	0.99	0.95–1.03	0.531

Logistic regression was used to calculate ORs and 95% CIs. Abbreviations: CT, clinical trial; DM, Dietary Modification Trial; HS, high school; HT, Hormone Therapy Trial; OS, observational study.

¹Adjusted for age (y), OS/CT, HT/DM, race/ethnicity (non-Hispanic White, Non-Hispanic Black/African American, Hispanic/Latina, Asian/Pacific Islander, American Indian/Alaskan Native, Unknown), education (≤HS, some post-HS, college degree, or higher), income (<$20K, $20 to <$35K, $35 to <$50K, $50 to <$75K, ≥$75K), smoking (never, past, current), total recreational physical activity, history of treated diabetes (no/yes), history of hypertension (no/yes), and parity (never pregnant/no term pregnancies, 1, 2, 3, 4, ≥5).

²Additional adjustment for total energy.

³Estimated by multiplying the biomarker-based calibrated total protein intake by the self-reported protein subtype proportion.
