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

Glycogen storage disease type II (GSD-II; Pompe disease; MIM 232300) is an inherited muscular dystrophy caused by deficiency in the activity of the lysosomal enzyme acid alpha-glucosidase (GAA). We hypothesized that chimeric GAA containing an alternative signal peptide could increase the secretion of GAA from transduced cells and enhance the receptor-mediated uptake of GAA in striated muscle. The relative secretion of chimeric GAA from transfected 293 cells increased up to 26-fold. Receptor-mediated uptake of secreted, chimeric GAA corrected cultured GSD-II patient cells. High-level hGAA was sustained in the plasma of GSD-II mice for 24 weeks following administration of an AAV2/8 vector encoding chimeric GAA; furthermore, GAA activity was increased and glycogen content was significantly reduced in striated muscle and in the brain. Administration of only 1 x 10(10) vector particles increased GAA activity in the heart and diaphragm for >18 weeks, whereas 3 x 10(10) vector particles increased GAA activity and reduced glycogen content in the heart, diaphragm, and quadriceps. Furthermore, an AAV2/2 vector encoding chimeric GAA produced secreted hGAA for >12 weeks in the majority of treated GSD-II mice. Thus, chimeric, highly secreted GAA enhanced the efficacy of AAV vector-mediated gene therapy in GSD-II mice.
