Sensitivity, specificity, and positive (PPV) and negative predictive values (NPV) of different single and combined CMR parameters for diagnosis of therapeutically relevant acute rejection (grade ≥1B) as proven by EMB. Abbreviations: ER = edema ratio, gRE = global relative enhancement, LGE = late gadolinium enhancement
