Case report: A finding of PVOD and PAH in first degree relatives suggests shared heritable risk and overlapping features of both pulmonary vascular diseases.

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
Pulmonary veno-occlusive disease (PVOD) is a rare form of pulmonary vascular disease that is difficult to distinguish clinically from pulmonary arterial hypertension (PAH). Multiple genes have been implicated in disease pathogenesis in PAH and PVOD and the diseases are thought to be genetically distinct. In this report we present a case of first-degree relatives with pathological evidence of PVOD and PAH. The index patient was diagnosed with PAH at age 42, was treated with escalating pulmonary vasodilator therapy, but eventually succumbed to her disease. On autopsy, her pathology was consistent with PAH. Her son was diagnosed with PAH at age 16, did well on pulmonary vasodilator therapy for over 10 years, but ultimately developed refractory right ventricular failure and received a heart and lung transplantation. Pathology of his explanted lung was consistent with PVOD, and genetic testing was negative for recognized variants that cause PAH or PVOD.
