  1. Data are presented as mean (standard deviation) or median (interquartile range). VTE: Venous thromboembolism, DVT: Deep vein thrombosis, CRP: C-reactive protein, IL-6: Interleukin 6, NT-pro-BNP: N-Terminal pro brain natriuretic peptide. Laboratory reference ranges: CRP < 5 mg/L; D-dimer < 0,50 mg/L (non-age-adjusted); Ferritin male patients 25–310 μg/L, female patients 10–155 μg/L (non-age-adjusted); IL-6 < 7,0 ng/L; plasma creatinine male patients 60–105 μmol/L, female patients 45–90 μmol/L; NT-pro-BNP male patients < 230 ng/L, female patients < 330 ng/L (non-age-adjusted); Troponin I male patients < 35 ng/L, female patients < 16 ng/L
