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

An elderly man with recurrent syncope was admitted with a globe rupture following a syncopal attack. After an initial unremarkable evaluation, the patient reported inversion of the room's wall clock during a bedside evaluation. This symptom is called reversal-of-vision metamorphopsia (RVM) and is a rare visual disturbance that typically results from organic processes localised to the retina and/or posterior cortex of the brain or in some cases is psychogenic in nature. In this case, both the syncope and RVM were caused by impaired circulation in the posterior cortex, and management included an antiplatelet agent, statin and permissive blood pressure targets, which resulted in the correction of RVM.
