Clinical implications of atrial natriuretic peptide amyloidosis.
Article in BMJ case reports, 2021. 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
A 74-year-old woman with a history of diastolic heart failure and refractory atrial fibrillation (AF) presented with unstable angina for coronary artery bypass grafting. Routine pathological analysis of tissue specimens obtained from the left atrial appendage revealed subendocardial and interstitial fibrosis and patchy amyloid deposits with Congo red staining demonstrating filamentous deposits. Mass spectrometry was consistent with isolated atrial amyloidosis (IAA). IAA in this patient was found incidentally on routine postoperative pathology, but likely contributed to significant morbidity. The established relationship between IAA with AF and diastolic heart failure underscores the relevance. Further delineating the pathogenesis has potentially immense implications for the future management of associated conditions. To bridge the gaps in the understanding, a standardised approach to diagnosis is needed to open the door to a large-scale study and further work toward establishing evidence-based management pathways.
