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 High efficacy disease modifying therapies (DMT) in the management of Multiple Sclerosis (MS) have a favorable effect on relapse rate and disability progression; however, they can expose patients to significant risks, such as progressive multifocal leukoencephalopathy (PML). Objective The study aims to investigate prognostic factors that can determine outcome in MS-related PML patients. Methods We conducted a literature review and meta-analysis of 194 patients from 62 articles in PubMed, SCOPUS and EMBASE. Results Out of 194 patients (66.5% women, 33.5% men), 81% had progression in their EDSS score by at least 1 point from the time of PML diagnosis (EDSS-P group). The remaining patients had either stable or improved EDSS (EDSS-S group). In univariate analysis, older age at the time of PML diagnosis was associated with higher probability of disability accumulation and worsening of EDSS by at least 1 point (mean age = 44.8, p = 0.046). After adjusting for other variables, age at time of PML diagnosis remained a significant predictive variable in the multivariable logistic model (OR = 0.93, 95% CI: 0.88-0.99, p = 0.037). Natalizumab is the most commonly associated DMT linked to PML, followed by fingolimod and others including dimethyl fumarate, ocrelizumab, alemtuzumab. Among the different treatments used, no therapeutic agent was found to be superior in improving post-PML EDSS. Conclusions Younger age and lower JCV viral load at the time of PML diagnosis were associated with better outcome in MS-associate PML, while none of the PML therapies was superior over the others or associated with favorable outcome.
