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: Therapeutic activation of endogenous utrophin, a homolog of dystrophin, represents a mutation-agnostic therapeutic strategy with considerable potential for treating Duchenne muscular dystrophy (DMD). However, the large size of current dCas9-based activation systems hinders efficient adeno-associated virus (AAV) delivery, and the long-term feasibility and therapeutic durability of such treatments remain uncertain. To overcome these limitations, we developed a muscle-targeted utrophin activation platform based on small activating RNA (saRNA), termed MyoAAV-saRNA. Methods: Screening of a panel of saRNAs targeting the Results: Following intravenous delivery of MyoAAV 2A-saRNA-257 in mdx mouse models, significant upregulation of utrophin mRNA was observed. This activation led to functional improvements, including partial restoration of the sarcolemma, histopathological amelioration (reduced centronucleation, inflammation, and fibrosis), and enhanced muscle strength. Conclusion: Collectively, these preclinical findings establish MyoAAV-saRNA as a promising and translatable platform for utrophin induction, highlighting its therapeutic potential for DMD.
