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

Hemophilia A is caused by a deficiency in the factor VIII (FVIII) gene. Constrained by limited packaging capacity, even the 4.3-kb B domain-deleted FVIII remained a challenge for delivery by a single adeno-associated viral (AAV) vector. Studies have shown that up to a 6.6-kb vector sequence may be packaged into AAV virions, which suggested an alternative strategy for hemophilia A gene therapy. To explore the usefulness of AAV vectors carrying an oversized FVIII gene, we constructed the AAV-FVIII vector under the control of a beta-actin promoter with a cytomegalovirus enhancer (CB) and a bovine growth hormone (bGH) poly(A) sequence. The CB promoter plus bGH signal was shown to be 3- to 5-fold more potent than the mini-transthyretin (TTR) promoter with a synthetic poly(A) sequence for directing FVIII expression in the liver. Despite the 5.75-kb genome size of pAAV-CB-FVIII, sufficient AAV vectors were produced for in vivo testing. Approximately 3- to 5-fold more FVIII secretion was observed in animals receiving AAV-CB-FVIII vectors than in those receiving standard-sized AAV-TTR-FVIII vectors. Both the activated partial thromboplastin time assay and the whole blood thromboelastographic analysis confirmed that AAV-FVIII vectors fully corrected the bleeding phenotype of hemophilia mice. These results suggest that AAV vectors with an oversized genome should be useful for not only hemophilia A gene therapy but also other diseases with large cDNA such as muscular dystrophy and cystic fibrosis.
