Table 3. Prediction Performance of the Gene-Model on Different Clinical Phenotypes (Biopsy Confirmed).

Prediction Sets	AR (prediction)	STA (prediction)	Total	Sensitivity (AR) or Specificity (Non-AR)
AR (N = 55)	49	6	55	89% Sensitivity
-A (N = 31)	25	5	31	81% Sensitivity
-1B (N = 22)	22	0	22	100% Sensitivity
-2 (N = 2)	1	1	2	Not calculated
Non-AR (N = 31)	3	28	31	90% Specificity
-STA (N = 19)	3	16	19	84% Specificity
-CMV+(N = 12)	0	12	12	100% Specificity

For all 86 samples in the prediction set, Sensitivity = 87%, Specificity = 90%.

AR: acute rejection (Grades 1–3); STA: stable (Grade 0).
