Imaging modality	Weighted mean sensitivity (%)	Weighted mean specificity (%)	NPV	PPV
Dobutamine echocardiographya	80	78	83	75
Thallium-201b	87	54	79	67

NPV negative predictive value, PPV positive predictive value

^aHigh-dose dobutamine has a higher sensitivity but similar specificity to low-dose dobutamine

^bThallium rest distribution has a higher specificity but similar sensitivity compared to Thallium reinjection
