  1. Model 1: unadjusted
  2. Model 2: adjusted for age and BMI as continuous variables
  3. Model 3: model 2 with additional adjustments for HbA1c and eGFR as continuous variables
  4. Low serum pancreatic amylase: < 29 U/L (vs. normal-high serum salivary amylase, ≥ 29 U/L)
  5. High serum 3-Hydroxybutyric acid ≥ 24 μmol/L (vs. normal serum 3-Hydroxybutyric acid, < 24 μmol/L)
  6. High serum acetoacetic acid ≥ 17 μmol/L (vs. normal serum acetoacetic acid, < 17 μmol/L)
  7. Low RQ: < 0.766 U/L (vs. normal-high RQ, ≥ 0.766 U/L)
  8. AA, acetoacetic acid; BMI, body mass index; eGFR, estimated glomerular filtration rate; 3-HBA, 3-Hydroxybutyric acid; RQ, respiratory quotient
