Table 4. The results of lasso regression model on the death outcome of the 66 critical patients with COVID-19.

Variables β OR*
CRRT 1.07 2.92
Tracheotomy -1.31 0.27
Convalescent plasma -1.41 0.24
Respiratory failure 1.61 4.99
Lung CT main performance 0.48 1.62
AKI 0.47 1.60
Neutrophil % 0.02 1.02

Note: AKI: acute kidney injury; WBC count: White blood cell count; LDH: Lactate dehydrogenase; CRP: C-reactive protein; *: OR value was calculated based on β, OR=eβ. Variables with positive β are risk factors of death outcome while those negative are protective.

In addition to the variables shown in the Table 4, these variables such as cough, dyspnea, hormone treatment, Invasive mechanical ventilation, acute myocardial injury, WBC count (109/L), Neutrophil count (109/L), Lymphocyte count (109/L), Albumin (g/L), LDH (U/L), maximum creatinine value during hospitalization(μmol/L), CRP (mg/L) and D-dimer (ug/mL) were also included into lasso model. However, their coefficients were shank to 0 by the model due to their negligible effects, therefore these variables were not included in the table.
