Table 5 Intra-observer and inter-observer CoVs for strain value measured by the same software (n = 64)

From: Left atrial strain reproducibility using vendor-dependent and vendor-independent software

  Intra-observer Inter-observer
Sct Scd Sr Sct Scd Sr
VSSLV 3.30% 1.52% 2.24% 3.49% 1.95% 2.57%
VISLV 0.71% 2.31% 1.15% 4.10% 3.67% 3.83%
VISLA 1.18% 0.05% 0.43% 0.85% 2.68% 1.32%
  1. Intra-observer and inter-observer CoVs for differences of Sct and Sr measured by VSSLV were significant (both, p < 0.05)
  2. Intra-observer and inter-observer CoVs for differences of Sct measured by VISLV had no significant differences (p > 0.05)
  3. Intra-observer and inter-observer CoVs for differences of strain measured by VISLA, were of no significant differences (p > 0.05)
