  1. National Telephone Health Interview Survey ‘German Health Update (GEDA)’ 2009.
  2. Cardiometabolic risk factors: hypertension, hyperlipidemia.
  3. CVD: angina pectoris, myocardial infarction, chronic heart failure and stroke.
  4. * Severity of diabetes was defined as: grade 1 = no diabetes-concordant comorbidity; grade 2 = any cardiometabolic condition without further diabetes-concordant comorbidity; grade 3 = any one diabetes-concordant end-organ complications (CVD or chronic renal disease or several visual impairment) irrespective of cardiometalic conditions; grade 4 =two or more diabetes-specific end-organ diseases irrespective of cardiometabolic conditions Grade 3 and 4 are irrespective of cardiometabolic conditions.
