The hazard ratio (HR) of hospitalization or death due to heart failure in individuals above versus below the threshold of central obesity (1a) and general obesity (2a) at different stages of diabetic nephropathy. WHtR, waist-height ratio; central obesity is considered if WHtR ≥ 0.5 for both sexes. BMI, body mass index; general obesity is considered if BMI ≥ 30 kg/m2 for both sexes. The multivariable Cox-regression model was adjusted for sex, age at onset of diabetes, duration of diabetes, glycated hemoglobin A1c, systolic blood pressure, HDL-cholesterol, triglycerides, smoking, lipid-lowering, antihypertensive and antidepressant medications, and estimated glomerular filtration rate. HR hazard ratio. CI confidence interval
