  • The 5y-Ad-DiaRem can be easily computed using an online tool accessible on our website (http://5y-Ad-DiaRem.nutriomics.org). Based on clinical values, the tool determines the score and gives information about the predicted outcome.

  • *Includes all antidiabetic treatments, regardless of pharmacological class (insulin included).

  • †HbA1c values in mmol/mol are as follows: 6.3% = 45 mmol/mol, 6.9% = 52 mmol/mol.

  • ‡The weight loss during the 1st year is calculated using the following formula: [(1-year body weight) − (baseline body weight)]/(baseline body weight) × 100.

  • §DR was defined according to American Diabetes Association criteria (5).
