Relative importance of the variables in the total cohort of COVID-19 patients analyzed using a new methodology for model interpretation suggested by Lundeberg and Lee [16,17]: SHAP (SHapley Additive ExPlanation) values.
| EM-6 | EM-7 | EM-8 | |
|---|---|---|---|
| Age | 50.9% | 36.2% | 17.7% |
| Female gender | 24.4% | 12.6% | 6.9% |
| Comorbidities | 24.7% | 16.5% | 12.5% |
| Oxygen saturation | - | 34.6% | 20.3% |
| CRP (μg/dL) | - | - | 12.5% |
| Leukocytes (103/L) | - | - | 8.9% |
| Lymphocyte/leukocyte ratio | - | - | 14.4% |
| D-dimer (mg/L) | - | - | 6.7% |
CRP = C-reactive protein mean. EM-6 = empirical model 6, EM-7 = empirical model 7, EM-8 = empirical model 8.
