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

Adeno-associated viral (AAV) vectors have shown great promise in gene delivery as evidenced by recent FDA approvals. Despite efforts to optimize manufacturing for good manufacturing practice (GMP) productions, few academic laboratories have the resources to assess vector composition. One critical component of vector quality is packaged genome fidelity. Errors in viral genome replication and packaging can result in the incorporation of faulty genomes with mutations, truncations, or rearrangements, compromising vector potency. Thus, sequence validation of packaged genome composition is an important quality control (QC), even in academic settings. We developed Fast-Seq, an end-to-end method for extraction, purification, sequencing, and data analysis of packaged single-stranded AAV (ssAAV) genomes intended for non-GMP preclinical environments. We validated Fast-Seq on ssAAV vectors with three different genome compositions (CAG-GFP, CAG-tdTomato, EF1α-FLuc), three different genome sizes (2.9, 3.6, 4.4 kb), packaged in four different capsid serotypes (AAV1, AAV2, AAV5, and AAV8), and produced using the two most common production methods (Baculovirus-
