Slow flow mimicking pulmonary embolism.
Article in BMJ case reports, 2023. 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
A man in his 70s in a rehabilitation hospital, post cerebral infarct, became acutely short of breath with reduced oxygen saturations and an elevated d-dimer.Non-occlusive filling defects were noted on the CT pulmonary angiogram in the proximal left pulmonary arteries. There was associated hypoplasia of the distal pulmonary arterial tree in the left hemithorax with left pulmonary vein stenosis. Review of previous imaging suggested this oligaemia was longstanding.Although filling defects in the pulmonary arteries usually correspond to embolic material, in our patient they were too dense to represent thrombus and probably represented flow-related artefacts in the setting of chronic air trapping.Given the associated volume loss, bronchiectasis and bronchial wall thickening in the left hemithorax Swyer-James-McLeod syndrome was thought to be the most likely underlying cause.
