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

Nocardiosis is an extremely rare, opportunistic, Gram-positive bacterial infection that has a high mortality rate in those patients who are immunocompromised in the presence of disseminated disease. We describe a case of an elderly lady being treated with high-dose corticosteroids for giant cell arteritis that presented with ischaemic optic atrophy. Subsequent deterioration was accompanied by the development of subretinal lesions. Further extensive evaluation discovered she had pulmonary nocardiosis with widespread dissemination. The case has several learning points, in particular: Subretinal abscesses maybe a harbinger of serious hitherto undiagnosed infection which portend a poor prognosis.Vital signs in the immunocompromised may appear to be normal in the presence of serious infection.
