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

Background and objectives: Dimethyl fumarate (DMF), an oral disease-modifying therapy with an established benefit and well-described safety profile, is among the most commonly used therapies for relapsing forms of multiple sclerosis. As of 31 December 2021, >560,000 patients have been treated with DMF, representing >1,190,000 person-years of exposure. Of these, 6413 patients (14,292 person-years) were from clinical trials. Methods and results: Progressive multifocal leukoencephalopathy (PML) has occurred in the setting of lymphopenia (<0.91 × 10 Discussion: DMF-related PML is rare but has occurred in the setting of lymphopenia, supporting the current recommendations for absolute lymphocyte count monitoring in all patients, regardless of age and time on therapy.
