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 |

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
