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

purposeTo describe a unique case of Purtscher-like retinopathy after a severe, complicated COVID-19 course which included development of disseminated intravascular coagulation (DIC). OBSERVATIONS: A 58-year-old male developed blurry vision in the left eye one week after being discharged from the hospital for severe COVID-19 pneumonia and DIC. He had been intubated and ventilated for 5 days. Fundus examination revealed optic nerve hyperemia in the right eye, optic nerve pallor in the left eye, arteriolar attenuation, multiple cotton wool spots and ill-defined areas of retinal whitening in the posterior pole in both eyes. His exam findings were most consistent with Purtscher-like retinopathy in both eyes. CONCLUSIONS AND IMPORTANCE: While several cases of central retinal artery and vein occlusion have been described in COVID-19 patients thus far, there has not been any reported cases of Purtscher-like retinopathy. To the best of our knowledge, this is the first case of Purtscher-like retinopathy in a patient who developed DIC during a severe COVID-19 infection.
