1 · What the graph read from it

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.

2 · The registry

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

Pulmonary arterial hypertension (PAH) has a diverse range of etiologies and carries significant morbidity and mortality. Here, we describe a case of reversible PAH caused by scurvy. A 45-year-old woman presented with shortness of breath and was found to be in acute right heart failure owing to PAH. Physical examination demonstrated features of scurvy. She initially required vasopressors, supplemental oxygen therapy, and PAH therapies, but rapidly improved with vitamin C supplementation. Vitamin C plays a role in the nitric oxide pathway targeted by most PAH approved agents and others involved in pulmonary vascular modulation such as hypoxia inducible factor regulation, representing a rare cause of PAH. Clinical scurvy is uncommon but can present as reversible PAH and right-sided heart failure.
