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.
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
Duchenne muscular dystrophy (DMD), the most prevalent lethal genetic disorder in children, is caused by mutations in the 2.2-MB dystrophin gene. Absence of dystrophin and the dystrophin-glycoprotein complex (DGC) from the sarcolemma leads to severe muscle wasting and eventual respiratory and/or cardiac failure. There is presently no effective therapy for DMD. Several lines of evidence have suggested that methods to increase expression of utrophin, a dystrophin paralog, show promise as a treatment for DMD. Adeno-associated viral (AAV) vectors are a promising vehicle for gene transfer to muscle, but microutrophin transgenes small enough to be carried by AAV have not been tested for function. In this study, we intravenously administered recombinant AAV (rAAV2/6) harboring a murine codon-optimized microutrophin (DeltaR4-R21/DeltaCT) transgene to adult dystrophin(-/-)/utrophin(-/-) (mdx:utrn(-/-)) double-knockout mice. Five-month-old mice demonstrated localization of microutrophin to the sarcolemma in all the muscles tested. These muscles displayed restoration of the DGC, increased myofiber size, and a considerable improvement in physiological performance when compared with untreated mdx:utrn(-/-) mice. Overall, microutrophin delivery alleviated most of the pathophysiological abnormalities associated with muscular dystrophy in the mdx:utrn(-/-) mouse model. This approach may hold promise as a treatment option for DMD because it avoids the potential immune responses that are associated with the delivery of exogenous dystrophin.
