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: Oculopharyngodistal myopathy (OPDM) is a rare hereditary muscle disease characterized by progressive ptosis, ophthalmoplegia, dysphagia, dysarthria, and distal muscle weakness. The genetic basis was identified in 2019 with CGG repeat expansions in the noncoding region of Case presentation: We present a patient with OPDM4 who had suffered progressive ptosis, external ophthalmoplegia, pharyngeal weakness, facial muscle weakness, and distal limb weakness over the past 20 years. Electromyography (EMG) revealed myogenic damage and normal H-reflex latency. A biopsy of the left biceps brachii revealed myogenic changes with atypical rimmed vacuoles in some muscle fibers. Screening for extra-muscular system involvement revealed no obvious involvement of the heart or central nervous system. Genetic analysis confirmed 126 CGG repeat expansions in Conclusion: This case broadens the spectrum of CGG repeat numbers in the
