  1. Variables included in the models were CK activity, age, BMI, cotinine, γ-GT, HbA1c, total cholesterol and TEE
  2. -, variable did not enter the model, CK creatine kinase, BMI body mass index, γ-GT γ-glutamyl transferase, TC total cholesterol, TEE total energy expenditure, HbA1c glycated hemoglobin
