Thresholds of the reliability measures (DSC, AVE, F1) for each category of WMH as well as confidence intervals of WMH volumes measured using QyScore® in comparison with experts’ consensus
| QyScore® markers | Thresholds | QyScore® 97.5% confidence intervals | ||||
|---|---|---|---|---|---|---|
| DSC | AVE (mL) | F1 | DSC | AVE (mL) | F1 | |
| WMH low (< 5 mL) | 0.27 | 2 | – | 0.284, 0.414 | 0.329, 0.666 | – |
| WMH medium (5–15 mL) | 0.51 | 5 | – | 0.647, 0.716 | 1.152, 2.518 | – |
| WMH high (15–30 mL) | 0.64 | 10 | – | 0.728, 0.771 | 2.648, 4.120 Ok | – |
| WMH very high (> 30 mL) | 0.67 | 15 | – | 0.761, 0.811 | 6.186, 10.417 | – |
| WMH whole sample | 0.47 | – | 0.3 | 0.616, 0.674 | – | 0.352, 0.3911 |
Bold numbers highlight the fact that the values were above or below the defined tresholds
