Q-Score performance compared to serum creatinine (SCr) and the estimated glomerular filtration rate (eGFR) and by recipient age. (A) The Q-Score showed superior performance compared with SCr and eGFR in discriminating AR from STA. (B) The performance of the Q-Score in different transplant patient age groups to differentiate AR from STA. Q-Score performed equally well in diagnosing pediatric transplant recipients (10 months to 18 years old) and in adult transplant recipients >18 years old. The AR prediction AUC of the ROC for pediatric patients was 100% (95% CI: 1.000–1.000; STA 25, AR 4) and the AUC of the ROC for adult patients was 99.8% (95% CI: 0.995–1.000; STA 127, AR 67).
