Unmasking a rare contrast reaction: acute non-cardiogenic pulmonary oedema after iohexol injection.
Article in BMJ case reports, 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
A woman with multiple comorbidities developed acute respiratory distress within minutes of intravenous iohexol administration for abdominal imaging. She presented with severe hypoxaemia, bilateral pulmonary crackles and diffuse opacities on chest imaging without evidence of cardiac dysfunction. Bedside echocardiography and brain natriuretic peptide levels excluded cardiogenic pulmonary oedema. A diagnosis of contrast-induced non-cardiogenic pulmonary oedema was made. She required non-invasive ventilation and supportive therapy with complete resolution over 1 week. This case highlights a rare, life-threatening but reversible reaction to iodinated contrast and underscores the importance of early recognition, prompt respiratory support and readiness with resuscitation equipment during contrast administration.
