Sequential Organ Failure Assessment Score for Evaluating Organ Failure and Outcome of Severe Maternal Morbidity in Obstetric Intensive Care

Table 2

Estimated probability of death of women with SMM, for each value of the total maximum Sequential Organ Failure Assessment score and the corresponding adjusted logistic regression equation.

Total maximum SOFA score	Probability of death (%)
1	0.27
2	0.44
3	0.72
4	1.16
5	1.87
6	3.00
7	4.78
8	7.53

24	99.47
Adjusted logistic regression equation:
Prob (death) = 1/(1 + exp(−(−6.380 + 0.484 × SOFA)))
