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 Aims: Charcot-Marie-Tooth disease X-linked Type 1 (CMTX1), caused by Methods: We retrospectively analyzed eight male patients, evaluating clinical signs, electrophysiology, and sural nerve biopsies. Pathogenicity of novel variants was assessed via bioinformatics, ChimeraX molecular modeling, and HeLa cell models focusing on protein localization and channel function (scratch-loading/DAPI assays). Results: Patients showed typical distal muscle atrophy and intermediate conduction velocities; three exhibited rare CNS white matter abnormalities. Two novel variants were identified: c.130dupT and c.124A > G. c.130dupT led to a complete "loss of expression" of the full-length Cx32 protein. c.124A > G resulted in significant cytoplasmic protein retention ( Interpretation: This study identifies two previously unreported
