  • aLinearity of associations between dietary scores and total mortality was tested using restricted cubic spline function. The P for linearity values for CHFP-2007, CHFP-2016, DASH, and HEI-2015 scores were 0.38, 0.35, 0.96, and 0.63, respectively.

  • bCox regression model was adjusted for age at 60-month survey, intervals between diagnosis and 60-month survey, and total energy intake.

  • cCox regression model was additionally adjusted for income, education, marriage, menopausal status at diagnosis, BMI at 60-month survey, physical activity at 60-month survey, ER, PR, HER2, TNM stages, comorbidity, chemotherapy, radiotherapy, and immunotherapy.
