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 investigate diffuse large B-cell lymphoma lesions with central nervous system (CNS) involvement in patients with vitreoretinal lymphoma (VRL) during long-term clinical courses. STUDY

designMulticenter, retrospective, and observational research.

methodsSeventy-one patients participated in this study, 45 were newly diagnosed VRL patients with CNS involvement initially or during follow-up of at least 12 months. We identified the CNS lesions in the patients that had VRL and investigated whether the onset sites of the CNS lesions were associated with the VRL lesions or optic pathways.

resultsThere were 42 patients with bilateral ocular lesions; 29 had unilateral lesions; 26 had incidental CNS lymphomas. Twenty patients developed recurrent CNS lymphoma 1-73 months after VRL diagnosis; 25 patients had no CNS lesions during the follow-up period. Most CNS lesions were in forebrain-originating tissues (95 lesions/total 124 CNS lesions total), followed by hindbrain-originating tissues, especially the cerebellum. Sixty-seven lesions were found in the non-optic pathway or non-visual cortex.

conclusionOver 60% of the VRL patients had CNS lesions. CNS involvement was not associated with the optic pathway or visual cortex, suggesting that clinicians should carefully examine CNS lesions occurring in both forebrain- and hindbrain-originating tissues during a patient's clinical course. Moreover, the CNS lymphomas that manifest as VRL show multifocal tumor development.
