Accuracy analysis of stand-alone and hybrid protocols for the diagnosis of significant CAD (by QCA ± FFR) on per-vessel (A) and per-patient (B) analysis. On a per-vessel basis, when positivity was defined by the presence of at least one positive test (either matched or mismatched findings), hybrid imaging had higher sensitivity than single modalities (P < 0.001 vs. MPS and CTCA), at the price of lower specificity (P < 0.001 vs. both MPS and CTCA) and accuracy (P < 0.001 vs. both MPS and CTCA). When only matched findings were considered positive, hybrid imaging increased accuracy (P < 0.001 vs. both MPS and CTCA) driven by higher specificity (P < 0.001 vs. both MPS and CTCA) but with lower sensitivity (P < 0.001 vs. MPS and CTCA).
