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: Facioscapulohumeral muscular dystrophy (FSHD) includes approximately 10%-30% sporadic cases, where de novo pathogenic variants are hypothesized to be associated with more severe phenotypes. However, the systematic clinical characteristics and natural history of these cases remain poorly defined. Methods: This retrospective observational cohort study was conducted at the Fujian Neuromedical Center, enrolling patients with genetically confirmed FSHD who were classified as de novo (dnFSHD) when no pathogenic D4Z4 contraction was detected in blood samples from either available parent. Clinical and genetic parameters at baseline and during subsequent evaluations were compared between dnFSHD and familial FSHD (fFSHD). The fFSHD cohort was matched for sex and disease duration. Mediation analysis was applied to explore the relationships among de novo pathogenic variants, the number of D4Z4 repeats, and disease progression. Results: A total of 92 patients with genetically confirmed FSHD who were classified as de novo cases were included, representing 17.8% of all FSHD type 1 cases. Compared with fFSHD, patients with dnFSHD exhibited an earlier age at onset (median: 10 years vs 16 years, Discussion: This study establishes dnFSHD as a distinct, high-risk FSHD subtype characterized by unique clinical features, with its severe phenotype primarily mediated by a shorter D4Z4 repeat array.
