Table 2 Methodological approach of reading procedures for testing inter- and intra-observer variability of echo-Doppler parameters
Assessment Procedures | |
|---|---|
A. Preliminary assessment | 1. Joint discussion on how to measure parameters by using sample echo studies not included in subsequent analysis |
| Â | 2. Preliminary reading session by the 2 readers of each couple on 4 cases for each echo-Doppler modality which were not included in the subsequent reproducibility analyses |
| Â | 3. Reciprocal training by the readers and standardization of measurements |
B. Final assessment | 1. First and second reading in random order by one of the observers of each couple |
| Â | 2. Blind independent reading of the second observer |
