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

Ocular disorders constitute a major component of the non-motor symptoms of Parkinson's disease (PD). Blurry vision is commonly associated with PD, but often challenging to interpret. The clinical spectrum of blurred vision is broad, and finding the underlying aetiology can be challenging. An incomplete diagnosis impedes therapeutic successes. We report two persons with PD who both experienced blurry vision, but each with a different underlying pathology that called for specific ophthalmological and neurological treatments. In case 1, the blurry vision was presumably caused by strabismus and convergence insufficiency, while case 2 had blurry vision partly due to palinopsia, a higher order visual processing deficit. Adequate treatment improved vision in both cases. Neurologists should be aware of the different underlying causes of blurred vision, should master the basic therapeutic approaches, and know when to refer a patient to the ophthalmology department.
