Data expressed as number (%) or mean ± SD. NCP, nucleocapsid; WNL, within normal limits. D-dimer was available for 99, fibrinogen, ferritin and von Willebrand factor-antigen for 98, lactate dehydrogenase for 95, and ST-2 and galectin-3 for 77 cases. The remaining parameters were available for all 100 cases.
