Comparison of diagnostic accuracy for detecting cytomegalovirus gastrointestinal disease between antigenemia assay and quantitative real-time polymerase chain reaction (n = 47)

	Sensitivity (95% CI)	Specificity (95% CI)	PPV (95% CI)	NPV (95% CI)
CMV real-time PCR	73.00% (57.4-84.4)	100% (92.5-100)	100% (92.5-100)	50.00% (36.1-65.9)
CMV antigenemia assay	64.90% (50.7-79.1)	100% (92.5-100)	100% (92.5-100)	43.50% (28.3-57.8)

CMV: Cytomegalovirus; PPV: Positive predictive value; NPV: Negative predictive value; PCR: Polymerase chain reaction.
