Table 2. Agreement among the four scans for each parameter measured using either local or global thresholding strategies.
| Quantitative parameter | Thresholding strategy | ICC (95% CI) |
|---|---|---|
| N. FD | Local | 0.978 (0.967–0.986) |
| Global | 0.901 (0.854–0.936) | |
| Area FD | Local | 0.950 (0.926–0.969) |
| Global | 0.446 (0.309–0.589) | |
| Average size FD | Local | 0.925 (0.889–0.952) |
| Global | 0.701 (0.591–0.796) | |
| FD density | Local | 0.958 (0.936–0.974) |
| Global | 0.843 (0.770–0.899) |
Values presented correspond to ICC. ICC, intraclass correlation coefficient; FD, flow deficits; N., number; CI, confidence interval.
