↵a Proportion of DL-CBCTA arterial segment visibility rated equal or superior to CTA. The data set (21 patients) includes all scans; the subset (12 patients) excluded inferior scans. The 98.75% CI of the 1-sided lower performance boundary is in parentheses (lower boundary is defined as 80% rated equal or superior).
↵b Statistically significant result.
