CI, confidence interval; HR, hazard ratio; Ref, reference; T, tertile.

^aModel 1 unadjusted.

^bModel 2 adjusted for age at diagnosis and total energy.

^cModel 3 same as Model 2 and further adjusted for body mass index, comorbidities, diet change, dietary pattern, education, FIGO stage, histological type, histopathologic grade, menopausal status, parity, physical activity, residual lesions, and smoke status.

^dP-value for linear trend calculated from category median values.
