When Phenotype Outspeaks Genotype: Uncommon Vascular Anomalies in Suspected Hereditary Hemorrhagic Telangiectasia Despite Negative Genetic Testing.
Article in Cureus, 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
Hereditary hemorrhagic telangiectasia (HHT) is an inherited vascular disorder characterized by abnormal blood vessel formation involving the skin and visceral organs. Establishing the diagnosis can be challenging, particularly in the absence of classic clinical manifestations or confirmatory genetic findings. We report the case of a 42-year-old woman who presented with acute epigastric pain and was found to have extensive vascular abnormalities involving the liver, lungs, aorta, and mesenteric circulation. She had no history of recurrent epistaxis, mucocutaneous telangiectasias, or family history of vascular disease, and genetic testing for known vascular disorders was negative. Despite the absence of typical clinical and genetic features, the distribution and extent of vascular involvement raised a strong suspicion for underlying HHT. This case highlights the potential for a broader phenotypic spectrum of HHT and underscores the limitations of current diagnostic criteria and genetic testing approaches.
