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

objectivesAdult-onset myotonic dystrophy type 1 (DM1) is a progressive, multisystemic disorder, characterized by distal muscle weakness and myotonia. As disease-modifying therapies emerge, robust and sensitive outcome measures are urgently needed. This study characterized the natural history of adult-onset DM1 over 2 years and evaluated quantitative MRI (qMRI) and clinical outcome measures for clinical trials.

methodsThis prospective, monocentric study assessed patients with genetically confirmed adult-onset DM1 and age-matched and sex-matched healthy controls at baseline and 12, 18, and 24 months. qMRI measured proton density fat fraction (PDFF, %) and T2

resultsThirty patients (median 38 years, 60% female, Muscular Impairment Rating Scale 3-4) and 30 matched controls were included. Baseline PDFF (%) was significantly higher in patients with distal (31.8% vs 5.9%, DISCUSSION: PDFF (%) is a sensitive, objective outcome measure for adult-onset DM1, detecting change within 6-month intervals. MFM32, MRC sum score, DM1-ActivC, and INQoL demonstrate meaningful deterioration over 12-24 months, supporting their combined use with qMRI as outcomes in future trials for adult-onset DM1.
