Condition | Measure of agreement (kappa) | 95% CI, lower limit-upper limit | P value |
Normal heart | 0.951 | 0.924 to 0.978 | <0.001 |
ASD | 0.735 | 0.488 to 0.9982 | <0.001 |
PDA | 0.904 | 0.773 to 1.35 | <0.001 |
Large VSD | 0.232 | −0.225 to 0.689 | 0.1 |
Restrictive VSD | 1.000 | NA | <0.001 |
VSD - PS physiology | 0.721 | 0.360 to 1.082 | <0.001 |
Interpretation of kappa values—value ≤0 indicates no agreement, 0.01–0.20 indicates slight agreement, 0.21–0.40 fair, 0.41–0.60 as moderate, 0.61–0.80 as substantial and 0.81–1.00 indicates almost perfect agreement.16 17
ASD, atrial septal defect; NA, not applicable; PDA, patent ductus arteriosus; VSD, ventricular septal defect; VSD-PS, VSD with pulmonic stenosis physiology.
