Strain measurements for manual and automated strain; GLS, GCS and GCS all slices, GRS and GRS all slices.
| Automated | Manual | p value | |
|---|---|---|---|
| GLS (%) | − 17.55 (− 20.10 to − 13.60) | − 16.37 (− 20.05 to − 12.30) | < 0.001 |
| GCS 3 slices (%) | − 19.51 (− 22.83 to − 15.13) | − 23.83 (− 28.63 to − 19.06) | < 0.001 |
| GCS all slices (%) | − 18.48 (− 21.79 to − 13.28) | < 0.001 | |
| GRS 3 slices (%) | 69.66 (54.38 to 88.44) | 20.45 (15.58 to 25.90) | < 0.001 |
| GRS all slices (%) | 70.51 (55.70 to 85.00) | < 0.001 |
Strain measurements are continuous variables represented by median and interquartile range. Wilcoxon signed rank test was used to calculate the p value for manual values and their respective automated values. Automated GCS and GRS all slices were compared to the manual method of obtaining the average of 3 slices. GCS, global circumferential strain; GLS, global longitudinal strain; GRS, global radial strain.
