Diagnostic value of contrast-enhanced ultrasonography for patent foramen ovale detection.
Article in Journal of thoracic disease, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: Patent foramen ovale (PFO) has been associated with migraine, cryptogenic stroke (CS), and hypoxemia. However, which examination method is most reliable remains controversial. This study sought to investigate the diagnostic value of contrast-enhanced ultrasonography (cU), including contrast-enhanced transcranial Doppler (cTCD), contrast transthoracic echocardiography (cTTE), and contrast transesophageal echocardiography (cTEE), for PFO; and to determine the best diagnostic strategy. Methods: This retrospective observational study included a total of 147 consecutive patients suspected PFO at The First Hospital of Shanxi Medical University between October 2019 and January 2022. The patients also underwent cTCD, cTTE, and cTEE examinations. The standard for the diagnosis of PFO was confirmation of the presence of PFO by color Doppler flow signals or contrast microbubbles (MBs) passing through the foramen ovale. Results: A total of 123 patients were diagnosed with PFO and 24 patients without PFO during the study period. The detectable rates of cTCD, cTTE, and cTEE were 120 (97.56%), 110 (89.43%), and 121 (98.37%), respectively. The sensitivity between cTCD and cTEE for PFO were comparable [97.56%, 95% confidence interval (CI): 92.5% to 99.4% Conclusions: The combination of cTCD and cTEE may provide a favorable strategy for the diagnosis of PFO.
