Results of weighted κ statistics for degree of stenosis, digital subtraction angiography versus CT angiography
| Overall % of agreement | Agreement among DSA reads | Agreement among CTA reads | Agreement between DSA and CTA | |
| Degree of ISR | 38.7 | κ=0.68 (95% CI 0.40 to 0.95) | κ=0.75 (95% CI 0.55 to 0.95) | κ=0.36 (95% CI 0.26 to 0.52) |
CTA, CT angiography; DSA, digital subtraction angiography; ISR, in-stent restenosis.
