Patient selection: patient admitted to hospital with COVID-19
More important risk factors for critical illness:
(1) oxygen saturation < 88% (odds ratio 7.0)
(2) first plasma D-Dimer > 2,500 in ng/mL (odds ratio 6.9)
(3) first serum ferritin > 2,500 in ng/mL (odds ratio 6.9)
(4) first serum C-reactive protein > 200 mg/L (odds ratio 5.8)
Parameters for CART analysis:
(1) peripheral capillary oxygen saturation (SpO2) in percent
(2) first serum procalcitonin (ProCal) in ng/mL
(3) first serum troponin in ng/mL
(4) first serum C-reactive protein (CRP) in mg/L
(5) age in years
(6) history of hypertension (HT)
