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

Since COVID-19 was first reported, different neurological complications have been acknowledged, but their description is constantly evolving. We report a case of concurrent tonic pupil and trochlear nerve palsy in this context. A 62-year-old man reported a 5-day history of binocular vertical diplopia and blurred vision in his left eye, noticing that his left pupil was dilated. He had suffered a flu-like syndrome 2 weeks before. Clinical exam showed a right trochlear nerve palsy and a left mydriatic pupil. MRI, X chest ray, and analytical results were normal. Antibodies for SARS-CoV-2 were positive (low IgM and high IgG titers). Antiganglioside antibodies were negative. A 0.125% pilocarpine test confirmed Adie's pupil diagnosis. The patient was treated with a tapered prednisone dose with resolution of his diplopia but no change in Adie's pupil. This is the first case reporting Adie's pupil as a postinfectious manifestation of COVID-19. An immune-mediated mechanism is presumed.
