| PT ratio | 1.225 | 1.065 to 1.435 | 0.004 | 1.169 | 1.020 to 1.364 | 0.024 |
| Total SOFA | 1.252 | 1.181 to 1.328 | 0.000 | 1.213 | 1.143 to 1.289 | <0.001 |
Total SOFA is the sum the four items (respiratory SOFA, cardiovascular SOFA, hepatic SOFA, renal SOFA). The score of total SOFA is defined as 2 if the total score exceeded 2.
