Variable Reader 1-3 Reader 2-3 Reader 3-0
D-shaped of left ventricle 0.72 0.46 0.78
Right ventricle dilatation 0.41 0.76 0.85
Right ventricle systolic function 0.46 0.62 0.81
Inferior vena cava plethora 0.36 0.53 0.63
Tricuspid regurgitation grade 0.32 0.5 0.77

Cohen’s Kappa: <0.2, slight agreement; 0.21∼0.4, fair agreement; 0.41∼0.6, moderate agreement; 0.61∼0.8, substantial agreement; 0.81∼1.0, almost perfect agreement.
