Association of ABMR score with conventional ABMR diagnosis leaving out mixed biopsies (Fisher exact test; P value<0.001)
| ABMR Score | ABMRa | No ABMRa | Total |
|---|---|---|---|
| ABMR score>0.2 | 64 | 66 | 130; PPV=0.49 |
| ABMR score<0.2 | 46 | 499 | 545; NPV=0.92 |
| Total | 110; sensitivity=0.58 | 565; specificity=0.87 | 675; accuracy=0.83 |
PPV, positive predictive value; NPV, negative predictive value.
For these calculations, biopsies conventionally assessed as mixed were not included.
