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.

Abstract

objectiveThis systematic literature review (SLR) was conducted to explore the role of serum neurofilament light chain (sNfL) as a biomarker in multiple sclerosis (MS) disease management.

methodsThe review was conducted in accordance with the recommendation laid by the Cochrane Handbook for Systematic Reviews. A comprehensive literature search was performed in key biomedical databases (EMBASE

resultsFollowing review of 1831 records, 75 studies from 180 publications were included in the review. The studies included in the SLR consistently demonstrated an association between higher sNfL levels and an increased risk of future relapses within 2 years and MS disease progression. Higher levels of sNfL were also linked to an increased likelihood of experiencing gadolinium-enhancing T1 and T2 lesions. Patients with lower sNfL levels had a higher likelihood of achieving no evidence of disease activity status. Furthermore, an inverse correlation was observed between sNfL levels and cognitive impairment as assessed via the Symbol Digit Modalities Test performance and Timed 25-Foot Walk scores.

conclusionThis SLR demonstrates the significance of sNfL as a sensitive biomarker for monitoring MS progression. Convenient and reliable sNfL measurement could benefit routine clinical practice, providing clinicians with a simple and effective tool to monitor disease and treatment response.
