| Diagnostic method for CMV detection | Sensitivity (%) | Specificity (%) | PPV (%) | NPV (%) |
| CMV-DNA-PCR from serum (n=47) | 65 | 100 | 100 | 79 |
| CMV-DNA-PCR of TS (n=47) | 70 | 100 | 100 | 82 |
| CMV-DNA-PCR >250 copies/mg of TS (n=11) | 79 | 83 | 92 | 63 |
| Owl eyes in H&E of TS (n=47) | 0 | 100 | 0 | 70 |
| IHC of TS (n=47) | 14 | 100 | 100 | 73 |
CMV, cytomegalovirus; IBD, inflammatory bowel disease; IHC, immunohistochemistry; NPV, negative predictive value;PPV, positive predictive value;TS, tissue sample.
