Diagnostic value of pulsed wave doppler in pneumothorax: a prospective study.
Article in Irish journal of medical science, 2024. 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
backgroundThe diagnosis of pneumothorax is usually made through clinical examination and radiography. Pulsed wave (PW) Doppler mode has not previously been used in the diagnosis of pneumothorax on chest USG.
aimsThe aim of this study is to present, for the first time, a new finding demonstrating pleural movements using PW Doppler mode and to examine the value of the new sonographic finding in the diagnosis of pneumothorax.
methodsWe investigated the presence of PW artifact in patients with and without pneumothorax using the high-frequency probe in PW Doppler. The Dogan's sign, defined as the absence of PW artifact, was then compared with lung sliding and the barcode sign in pulsed wave Doppler for the diagnosis of pneumothorax.
resultsOf the 141 patients, 39 were in the pneumothorax group. The sensitivity and specificity of the Dogan's sign in the diagnosis of pneumothorax were 95.12% and 99.3%, respectively, in this study. The sensitivity and specificity of lung sliding were 95.12% and 98.08%, respectively; the sensitivity and specificity of the barcode sign were 92.86% and 98.08%, respectively, in the diagnosis of pneumothorax by ultrasonography in this study.
conclusionPW Doppler is a useful tool in the diagnosis of pneumothorax. It has a high sensitivity and specificity for the detection of pneumothorax. It is also superior to both lung sliding and the barcode sign in detecting pneumothorax. The Dogan's sign can be used safely in the diagnosis of pneumothorax, together with lung sliding and the barcode sign.
