  1. Glycemic DMT2 refers to patients classified as diabetics if HbA1c exceeds 48 mmol/mol regardless of any treatment. The Treatment DMT2 sub-population includes all subjects with HbA1c below 48 mmol/mol but received antidiabetic medical treatment (drugs or insulin)
  2. *The p-values are given as nominal values. Only p-values <0.001 can be considered significant after Bonferoni correction for multiple testing
