Age-adjusted HR (95% CI)	Referent	1.09 (0.93 to 1.29)	0.98 (0.83 to 1.16)	1.19 (1.01 to 1.41)	.14

^aTwo-sided test for trend performed by entering the quartile of the score as an ordinal variable in Cox proportional hazards regression.

^bHazard ratios from Cox proportional hazards regression adjusted for age at diagnosis (continuous), cohort (Health Professionals Follow-Up Study, Nurses’ Health Study; also adjusted for sex), race and ethnicity (White, Black, other, missing), smoking status (never, past, current, missing), diagnosis period (1986-1999, 2000-2014), cancer stage (localized, locally advanced, metastatic, unknown), and total energy intake (continuous).

^cFurther adjusted for body mass index (continuous) and diabetes status (no or unreported, short-term diabetes [≤4 y], long-term diabetes [>4 y]).
