Table 4

Diagnostic performance of the tested marker combination for detection of late-onset neonatal pneumonia.

Parameter	AUC	95% CI	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
Salivary IL-6+ MPV	0.951	0.921-0.981	82.86	94.29	93.55	84.62
Salivary IL-6+ CRP/MPV	1.0	1.0-1.0	100	100	100	100
Serum IL-6+ MPV	0.952	0.928-0.976	82.86	94.29	93.55	84.62
Serum IL-6+ CRP/MPV	1.0	1.0-1.0	100	100	100	100

IL-6: interleukin-6; MPV: mean platelet volume; CRP: C-reactive protein.
