^aResults from the Nurses’ Health Study (NHS) and the NHS II were pooled using the fixed-effect model with inverse-variance weighting per 25-percentile increment in the 4 dietary scores (25 points for the HEI-2015, 9 points for the AMED, 18 points for the HPDI, and 25 points for the AHEI). Multivariable analysis adjusted for age, body mass index, physical activity, smoking status, alcohol intake, menopausal status, oral contraceptive use (NHS II only), calendar year marital status, living alone or with others, family history of myocardial infarction, total energy intake, multivitamin use, aspirin use, and family history of diabetes.

^bNon-Hispanic white includes non-Hispanic women with southern European/Mediterranean ancestry, Scandinavian ancestry, and other Caucasian ancestry. Minority racial/ethnic groups include non-Hispanic black, Hispanic, and other racial/ethnic women. Other includes women not classified as non-Hispanic white, non-Hispanic black, or Hispanic, such as Asian and American Indian.
