- The degree of occlusion as per the nasopharyngoscopic study: 0 = no obstruction (0–25%), 1 = partial occlusion (25–75%), and 2 = complete occlusion (≥76%)
- Interpretation of kappa index: < 0, no agreement; 0–0.19, poor agreement; 0.20–0.39, fair agreement; 0.40–0.59, moderate agreement; 0.60–0.79, substantial agreement; 0.80–1.00, almost perfect agreement
