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

Recombinant adeno-associated virus (rAAV) has become a prominent vector for clinical use. Despite an increase in successful clinical outcomes, the amount of high-quality rAAVs required for clinical trials and eventual commercial demand is difficult to produce, especially for genetic diseases that are prevalent or require high doses. Many groups are focused on establishing production processes that can produce sufficient rAAV while maintaining potency and quality. Our group used a novel production platform to increase our yield of rAAV5. This production platform uses tetracycline-enabled self-silencing adenovirus (TESSA) to deliver the wild-type AAV replication and capsid genes alongside the adenovirus helper genes necessary for production. Here, we describe our efforts to evaluate the TESSA platform in house. We conducted numerous experiments to determine the optimal conditions for producing rAAV5 from the TESSA production system. We then produced rAAV5 from the TESSA system to compare against rAAV5 produced from triple transfection. Ultimately, we generated data that showed that the vector genome yield of rAAV5 produced with TESSA was >20-fold higher than rAAV5 produced with triple transfection. Additionally, our data show that quality as well as potency in mice of rAAV5 produced with the TESSA system and by triple transfection are equivalent.
