Correlation between ventilator-associated events and ventilator-associated lower respiratory tract infections

	VAC, n = 262	IVAC, n = 134	pVAP, n = 65
VAP	71 (27.1)	58 (43.3)	56 (86.2)
No VAP	191 (72.9)	76 (56.7)	9 (13.8)

	KVAP-VAC = 0.03 (0–0.11)	KVAP-IVAC = 0.15 (0.07–0.23)	KVAP-pVAP = 0.27 (0.18–0.35)
VAT	6 (2.3)	3 (2.2)	3 (4.6)
No VAT	256 (97.7)	131 (97.8)	62 (95.4)

Data are numbers (%)

The correlation between ventilator-associated events and VAT could not be calculated because of the small number of patients with VAC and VAT (n = 6)

IVAC, infection-related ventilator-associated condition; p, probable; VAC, ventilator-associated condition; VAP, ventilator-associated pneumonia; VAT, ventilator-associated tracheobronchitis
