Impact of interleukin 6 levels on acute lung injury risk and disease severity in critically ill sepsis patients

Table 5 Receiver operating characteristic curve analysis for the prediction of acute lung injury and multiple organ dysfunction syndrome using plasma interleukin 6 levels

Outcome	Cut-off in pg/mL	Sensitivity	Specificity	PPV	NPV	AUC (95%CI)
ALI	92.5	76.3	80.0	72.7	82.9	0.84 (0.75-0.93)
MODS	118.7	72.4	85.2	75.0	83.8	0.82 (0.72-0.91)

ALI: Acute lung injury; AUC: Area under the curve; CI: Confidence interval; MODS: Multiple organ dysfunction syndrome; NPV: Negative predictive value; PPV: Positive predictive value.
