Performance of Six Equations for Estimating Resting Energy Expenditure in Patients With Type 2 Diabetes

Inclusion Criteria: * Patients with type 2 diabetes * Available resting energy expenditure assessed by indirect calorimetry Exclusion Criteria: * data on ongoing therapy (e.g. lifestyle measures with or without approved drugs), anthropometric or laboratory parameters (including white blood count, estimated glomerular filtration rate, TSH), or REE assessed by the means of indirect calorimetry could not be retrieved * presenting with conditions known to affect indirect calorimetry (e.g. patients with strenuous exercise on the day before, asymptomatic patients with severe chronic kidney disease (eGFR \< 30 ml/min/ 1.73 m2), increased white blood count, or subnormal TSH)
