Dotted horizontal line indicates the positive/negative cutoffs for the molecular scores. The y-axes are the scores for the two samples compared for the TCMR, ABMR, and Rejection classifiers (a number between 0 and 1.0) or the geometric mean of the expression of the AKI transcripts (IRRATs). The x-axis is the mean of classifier or IRRAT scores. ABMR, antibody-mediated rejection; AKI, acute kidney injury; IRRAT, acute kidney injury transcripts; TCMR, T cell–mediated rejection.
