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

The single-stranded genome of adeno-associated viral (AAV) vectors is one of the key factors leading to slow-rising but long-term transgene expression kinetics. Previous molecular studies have established what is now considered a textbook molecular model of AAV genomes with two copies of inverted tandem repeats at either end. In this study, we profiled hundreds of thousands of individual molecules of AAV vector DNA directly isolated from capsids, using single-molecule sequencing (SMS), which avoids any intermediary steps such as plasmid cloning. The sequence profile at 3' ends of both the regular and oversized vector did show the presence of an inverted terminal repeat (ITR), which provided direct confirmation that AAV vector packaging initiates from its 3' end. Furthermore, the vector 5'-terminus profile showed inconsistent termination for oversized vectors. Such incomplete vectors would not be expected to undergo canonical synthesis of the second strand of their genomic DNA and thus could function only via annealing of complementary strands of DNA. Furthermore, low levels of contaminating plasmid DNA were also detected. SMS may become a valuable tool during the development phase of vectors that are candidates for clinical use and for facilitating/accelerating studies on vector biology.
