Ventilator Weaning Failure Induced by Oral Beraprost in a Patient after Femoral Endarterectomy: A Case Report.
Article in Annals of vascular diseases, 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
Beraprost sodium, an oral prostacyclin analog, is a systemic vasodilator whose role in ventilator weaning failure has not been widely described. We present the case of a 90-year-old man with extensive atelectasis who received beraprost for critical limb ischemia and developed refractory ventilator weaning failure. Each weaning attempt was interrupted by recurrent episodes of tachypnea and marked hypoxemia. These events resolved after discontinuation of beraprost; however, reintroduction of the drug reproduced identical respiratory deterioration, suggesting a potential association. Oral beraprost may contribute to recurrent hypoxemia and tachypnea in patients with severe pre-existing ventilation-perfusion mismatch, potentially leading to ventilator weaning failure.
