ROC analysis for clinical and laboratory findings of controls and A+B groups

Control–AB	AUC	SE	P-value	95% CI	Cutoff	Sensitivity (%)	Specificity (%)
FEV1 (%)	0.904	0.031	≤0.001	0.844–0.964	91.00	90.9	84.1
FEV1/FVC (%)	1.000	0.000	≤0.001	1.000–1.000	73.00	100	100
CRP (mg/L)	0.414	0.056	0.161	0.303–0.525	0.23	60.6	42.0
NF-κB (ng/mL)	0.330	0.053	0.006	0.226–0.435	3.37	30.3	42.0
LL-37 (pg/mL)	0.634	0.070	0.029	0.498–0.770	323	69.7	50.7

Note: Bold type indicates specificity and/or sensitivity values are greater than 80%.

Abbreviations: ROC, Receiver operating characteristic; CRP, C-reactive protein; NF-κB, nuclear factor-kappaB; AUC, area under the curve.
