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

VSSLV −0.38 (−2.44, 1.68) − 0.26 (−3.76, 3.24) 0.64 (− 3.05, 4.33) − 0.40 (− 3.31, 2.50) −0.33 (−5.35, 4.68) 0.73 (−5.37, 6.84)
VISLV 0.10 (− 3.11, 3.31) − 0.54 (− 5.86, 4.78) 0.44 (− 5.73, 6.60) 0.60 (−4.45, 5.65) 0.86 (−11.43, 13.14) −1.45 (− 14.81, 11.90)
VISLA − 0.18 (− 2.68, 2.32) 0.01 (− 4.12, 4.15) 0.17 (− 4.95, 5.28) −0.13 (− 3.98, 3.73) 0.64 (−9.84, 11.11) −0.51 (− 11.66, 10.64)
  1. The bias for value measurement by VISLA was smaller than that by VSSLV and VISLV
