Sequential Oxygenation Index and Organ Dysfunction Assessment within the First 3 Days of Mechanical Ventilation Predict the Outcome of Adult Patients with Severe Acute Respiratory Failure

Table 6

Comparison of cutoff value, sensitivity, specificity, AUC*, and P values between OI and physiological severity scores.

Factor	Cutoff	Sensitivity	Specificity	AUC	𝑃 values
SOFA* score	5.5	53%	73%	0.647	0.01
Day 3 OI*	3.79	69%	71%	0.724	<0.001

 *AUC: Area under curve, SOFA: Sequential Organ Failure Assessment, OI: oxygenation index.
