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 report a case of subretinal abscess as the initial presentation of systemic nocardiosis. The patient was a known case of chronic inflammatory demyelinating polyneuropathy and on long-term immunosuppressants. He presented with a rapidly progressive, unilateral decline in visual acuity in the right eye. Dilated fundus examination showed a large whitish subretinal lesion. A working diagnosis of subretinal abscess was made. The appearance was highly suspicious for
