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

We present a case of a woman at 31 weeks and 3 days of gestation, who developed a sudden and severe headache and loss of vision in her left eye. Magnetic resonance imaging (MRI) of the brain revealed a subarachnoid bleed secondary to a right parieto-occipital arteriovenous malformation (AVM). She was conservatively managed and subsequently transferred to our institution for multidisciplinary care. The patient underwent a cesarean section at 34 weeks and 5 days of gestation followed by gamma knife surgery 6 days after. Cerebral AVMs, although relatively rare, have the propensity to cause potentially fatal outcomes. Neurological symptoms in a pregnant woman warrant investigations for early diagnosis and management, due to its associated morbidity and mortality. The management of cerebral AVMs in pregnancy is decided after weighing the benefits of treatment against the risk of bleeding. A multidisciplinary approach should be adopted due to the complexity of the condition.
