Interobserver agreement of an ED PoCUS video training dataset of normal appendix and appendicitis in children.
Article in The ultrasound journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEducational video datasets can be an effective method for training in emergency department (ED) point-of-care ultrasound (PoCUS). A video dataset for normal appendix and appendicitis in children using ED PoCUS images was developed to assess interobserver agreement, as measured by Cohen's Kappa on key sonographic findings.
methodsThree sets of 25 ED PoCUS videos were selected and curated from pediatric patients with normal appendix and acute appendicitis. Four participant ED sonologist-physicians were trained on the first set of 25 videos showing normal appendix or normal bowel in patients without appendicitis to note if normal appendix was seen in any part or in it's entirety from tip-to-cecum. They were then tested on the second set of similar videos. A third set of 25 videos from patients who had appendicitis where participant sonologists were asked to note if appendicitis was present or absent, with and without appendicolith or perforation. Cohen's Kappa was calculated in aggregate and stratified by experience vs. novice against a senior sonologist-physician aware of all patient outcomes for visualization of: 1. any part of normal appendix, 2. normal appendix visualized from tip to cecum 3. any part of appendicitis, 4. appendicolith, 5. appendiceal perforation.
resultsCohen's Kappa for any part of normal appendix, 0.71, 95% CI (0.58-0.85); normal appendix tip-to-cecum, 0.43, 95% CI (0.19-0.67), appendicitis, 0.53, 95%CI (0.34-0.70), appendicolith, 0.63, 95%CI (0.43-0.84), perforated appendicitis, 0.46, 95%CI (0.22-0.70). Stratified by experienced vs. novice: any part of normal appendix, 0.75 vs. 0.68; normal appendix tip-to-cecum, 0.50 vs. 0.36; appendicitis, 0.78 vs. 0.31; appendicolith, 0.75 vs. 0.5; perforated appendicitis, 0.5 vs 0.42.
conclusionsThis educational video dataset may be used to train sonologist-physicians in ED PoCUS scanning for normal appendix and appendicitis in children. Sonologist experience affected interobserver agreement with respect to visualization of entire normal appendix and appendicitis.
