A novel scoring system for early assessment of the risk of the COVID-19-associated mortality in hospitalized patients: COVID-19 BURDEN

Table 2 Variables, which remained in the final multiple logistic regression model to predict the risk of mortality during hospitalization

Variables	Coefficient	Coefficient (SE)	P value	Odds ratio (95% CI)	Lower –Upper 95% CI
DBP	0.794	0.360	0.027	2.212	1.093–4.479
PT	0.761	0.349	0.029	2.140	1.079–4.242
BUN	1.254	0.356	< 0.0001	3.503	1.744–7.039
LDH	1.066	0.369	0.004	2.903	1.408–5.987
CRP	1.017	0.418	0.015	2.766	1.220–6.271
84% ≤ O2 Sat ≤ 90%	0.799	0.652	< 0.0001	2.223	0.620–7.975
O2 Sat < 84%	2.218	0.604	< 0.0001	9.189	2.811–30.040

O2 Sat > 90% was used as reference index in O2 saturation category. Formulation of integer risk score for each category was based on the strength of contribution to logistic equation based on the coefficient (for example, the coefficient of O2 Sat < 84% is 2.218; therefore, an integer score of 2 was given. Coefficient of BUN is 1.254; therefore, an integer score of 1 is given)
DBP diastolic blood pressure, PT prothrombin time, BUN blood urea nitrogen, LDH lactate dehydrogenase, CRP C-reactive protein, O2 Sat O2 saturation
The Italic was merely used to show the elevate the p values above other values and make a distinction
