1

Change in odds of intermediate flora or BV compared to normal flora (Nugent: 0–3) per 10-unit increase in corresponding dietary index value.

2

= 1719 in crude analyses and n = 1644 in adjusted analyses.

3

aOR, adjusted OR; BV, bacterial vaginosis; cOR, crude OR; GI, glycemic index; GL, glycemic load; HEI, Healthy Eating Index; NNR, Naturally Nutrient Rich.

4

Models adjusted for age, race, education, cigarette smoking, alcohol use, BMI, douching frequency, hormonal contraceptive use, and number of sex partners.

5

Spline term with node at 70; OR correspond to the slopes < and > HEI = 70.

6

for the difference between slopes < and > HEI = 70 are 0.13 and 0.10 for crude and adjusted intermediate flora and 0.10 and 0.08 for crude and adjusted BV, respectively.
