  1. AICR American Institute for Cancer Research, DPP Diabetes Prevention Program, WCRF World Cancer Research Fund. Results with significant p-values (p<0.05) are bolded. Data shown are HR for incident diabetes per one-point positive change in Score
  2. aThe N included examining Score change between years 0 and 1 is slightly lower than the time-dependent Score analysis because some participants were missing year 1 nutrition data but have subsequent years’ nutrition data.
  3. bDiabetes is defined based on the 1997 American Diabetes Association criteria: fasting plasma glucose ≥ 7 mmol/L (≥ 126 mg/dL) measured every six months or 2-hour plasma glucose ≥ 11.1 mmol/L (≥200 mg/dL) after a 75 g oral glucose load [21].
  4. cYear 0 through the end of the Diabetes Prevention Program represents a mean follow-up time of 3.2 years
  5. dBase model adjusted for age, sex, and baseline risk score
  6. eMultivariate model adjusted age, sex, race/ethnicity, marital status, family history of type 2 diabetes, smoking status, years of education, hormone therapy, baseline total caloric intake, and baseline risk score
  7. fDPPOS follow-up through January 2014 was included in the study, representing a mean follow-up time of 15 years
