Abbreviations: AHEI-2010, Alternative Healthy Eating Index-2010; BMI, body mass index (calculated as weight in kilograms divided by height in meters squared); HEI-2020, Healthy Eating Index-2020; HR, hazard ratio; NA, not applicable.
Score ranges were 0 to 100 for HEI-2020 and 0 to 110 for AHEI-2010. The P for interaction was .33 for HEI-2020 and .67 for AHEI-2010.
With obesity.
The Cox proportional hazard model was adjusted for age (years), education (≤high school graduate, some college, ≥college graduate), annual household income (<$25 000, ≥$25 000, or unknown), physical activity in the year before diagnosis (yes or no), smoking status (never, current, or former smoker), study site (Southwest, Southeast, or North), and histotype (HGSOC or other).
Quartile 1 and quartile 4 indicate low and high adherence to dietary guidelines, respectively.
