Exploring Inter-Rater Agreement in Classification of Radiological Features of Tension in Adults With Primary Spontaneous Pneumothorax.
Observational study in Emergency medicine Australasia : EMA, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo explore agreement between emergency physicians in classifying chest x-rays (CXR) of patients with primary spontaneous pneumothorax (PSP) as showing the presence/absence of so-called radiological tension features.
methodsObservational study. Five emergency physicians blinded to patient characteristics, radiologist report, patient outcome and other reviewers' classification assessed each of 80 PSP CXR and classified them as showing radiological tension features or not. Analysis using Krippendorff's Alpha (K-Alpha).
resultsInter-rater agreement was 0.524 (95% CI: 0.400-0.623)-consistent with poor agreement.
conclusionInterpretation for radiological tension features had poor inter-rater reliability, which seriously changes their appropriateness as drivers for interventional management.
