Inter rater reliability among lung ultrasound experts
Chest-indrawing pneumonia cohort# κ | No pneumonia cohort¶ κ | |
Overall pneumonia | 0.915 | 1+ |
Consolidation | 0.915 | 1+ |
Pleural effusion | 1+ | |
Interstitial pattern | 0.901 | 0.635 |
Obstructive atelectasis | 0.746 |
Testing of κ only signifies that the level of inter rater reliability differs from what would occur by chance (κ=0). Thus, p-values are not noted for κ results. #: n=226. ¶: n=40. +: based on small counts for one of the two possible categories of inter rater reliability, with two or fewer children in the smaller category.
