Expansion of pulmonary arteriovenous malformations after grand mal seizures and other circumstances of PAVM growth.
Article in BMJ case reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 asymptomatic pulmonary arteriovenous malformation (PAVM) discovered incidentally on admission developed recurrent generalised seizures. Immediately after, the PAVM demonstrated marked expansion, and was safely resected. Congenital PAVMs (associated with hereditary haemorrhagic telangiectasia or sporadic) are considered stable lesions that exhibit very slow growth if at all. A review of the literature reveals all circumstances of accelerated growth of PAVM (puberty, pregnancy, postpartum, pulmonary hypertension) and suggests a novel mechanism of seizure-associated expansion. This is important because the size and rapid growth of PAVMs correlate with the potential for rupture and other ominous complications such as right to left shunt and paradoxical emboli. The new seizures-PAVM progression association mandates recognition since the risk of seizures in patients with PAVM is substantial. Our observations strongly suggest the need to monitor PAVM in patients with or without haemorrhagic telangiectasis by repeated imaging after generalised seizures to evaluate potential expansion and risk.
