Accuracy of Resident-Performed Point-of-Care Lung Ultrasound Examinations Versus Chest Radiography in Pneumothorax Follow-up After Tube Thoracostomy in Rwanda.

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
objectivesThe aim of this study was to evaluate the accuracy and timeliness of resident-performed point-of-care lung ultrasound (LUS) examinations for the follow-up of pneumothorax (PTX) after tube thoracostomy.
methodsAfter brief training, Rwandan surgical residents blinded to chest radiography (CXR) performed and interpreted LUS examinations for PTX in participants undergoing CXR for PTX follow-up. Treating clinicians interpreted CXR for the presence of PTX for therapeutic decisions. Lung ultrasound was later reviewed by ultrasound experts, and CXR was reviewed by a radiologist. We defined expert LUS interpretation as the reference standard. The sensitivity and specificity of resident-performed LUS examinations for diagnosing PTX were calculated. We assessed agreement between trained resident versus expert LUS and clinician versus radiology CXR using the Cohen κ coefficient. We compared the time to results between LUS and CXR.
resultsOver an 8-month period, 51 participants were enrolled. Compared to expert LUS interpretation, the sensitivity and specificity (95% confidence intervals) of resident LUS were 100% (85%-100%) and 96% (82%-100%), respectively, whereas the sensitivity and specificity of clinician-interpreted CXR were 48% (27%-69%) and 100% (88%-100%). The agreement between resident and expert LUS was excellent (κ = 0.96), whereas the agreement between clinician and radiologist CXR was only moderate (κ = 0.60). The time to results was significantly longer for CXR than LUS (mean, 1335 versus 396 minutes; P = .0001).
conclusionsA resident-performed LUS examination was a quicker imaging modality with superior sensitivity compared to clinician-interpreted CXR for PTX follow-up after tube thoracostomy in this Rwandan study. Lung ultrasound can be a valuable imaging tool for PTX follow-up, especially in resource-limited settings.
