Table 3 Participant imaging data split by type of rater
Rater | Number of studies assigned an LVEF | Number of studies of insufficient quality for LVEF estimation | Mean estimation of LVEF ± SD |
|---|---|---|---|
ML model | 91 | 47 | 0.39 ± 0.11 |
Level III expert visual LVEF on randomized single videos, averaged per patient | 120 | 18 | 0.40 ± 0.13 |
Level III expert segmentation LVEF on randomized single videos, averaged per patient | 67 | 71 | 0.40 ± 0.14 |
Level III expert visual LVEF, accounting for all videos for a participant | 124 | 14 | 0.40 ± 0.13 |
Level III expert segmentation LVEF, accounting for all videos for a participant | 72 | 66 | 0.40 ± 0.12 |
Derived LVEF from echo reports | 138 | 0 | 0.39 ± 0.12 |
