Sensitivity, specificity, PPV, NPV, LR+, and LR– of BDG and PCT used in combination for the diagnosis of candidaemia over bacteraemia in the study population

	No./total patients
Cut-off	Candidaemia (TP/total)	Bacteraemia (TN/total)	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)	LR+	LR–
BDG ≥80 pg/ml and/or PCT <2 ng/ml	70/73	56/93	96	60	65	95	2.41	0.07
BDG ≥80 pg/ml and PCT <2 ng/ml	48/73	91/93	66	98	96	78	30.58	0.35

BDG (1,3)-β-d-glucan, LR+ positive likelihood ratio, LR– negative likelihood ratio, NPV negative predictive value, PCT procalcitonin, PPV positive predictive value, TN true negatives, TP true positives
