Model performances with different feature combinations. We use RF to identify the top eight features, and conduct experiments to evaluate model performances with different feature combinations.

Model	Feature	AUC
1	BMI, age	$0.550\pm 0.079$
2	BMI, age, Na	$0.658\pm 0.176$
3	BMI, age, Na, Lymphocyte	$0.670\pm 0.157$
4	BMI, age, Na, Lymphocyte, INR	$0.742\pm 0.137$
5	BMI, age, Na, Lymphocyte, INR, WBC	$0.738\pm 0.157$
6	BMI, age, Na, Lymphocyte, INR, WBC, Platelets	$0.783\pm 0.157$
7	BMI, age, Na, Lymphocyte, INR, WBC, Platelets, Mg	$0.799\pm 0.138$
