1
Logistic regression models were fitted separately for each nutrient and adjusted for fat, carbohydrate, protein, age, race, BMI (BV only), income, education (BV only), douching, contraceptive pill use, and alcohol intake (BV only).
2
Intakes of vitamins A, C, D, β-carotene, lycopene, fiber, zinc, and iron were not associated with BV or severe BV (data not shown).
3
A P-value ≥ 0.05 indicates a nonsignificant trend for association between a nutrient and BV categories.
