Categorical data are presented as numbers (percentages), and continuous data are given as median (25th; 75th percentiles). The number of subjects with additionally missing data was n = 9 for hospital stays during last 12 months, n = 58 for hs-CRP, n = 2 for leukocytes, and n = 9 for fibrinogen (Clauss).
