  1. Abbrevations: 1: potassium concentration (mmol/l); lower potassium probably as marker for diuretic therapy, 2: creatinine concentration (mg/dl), 3: body mass index, 4: Myocardial infarction, 5: Chronic obstructive pulmonary disease, 6 De ritis ratio: De ritis-ratio as marker for liver damage, e.g. ethanol intake 7 Urea concentration (mg/dl),
