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.
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 major challenge of recombinant adeno-associated virus (rAAV) vectors is host immunological barriers. Compared to the neutralizing antibody and the cytotoxic T lymphocyte response, the host immune responses induced by unsatisfactory rAAV manufacturing were largely ignored previously. rAAV vector production usually requires large amounts of plasmid DNAs. The DNA are commonly isolated from the DH5α bacterial strain, which contains lipopolysaccharide (LPS) contamination. LPS, also named endotoxin, in plasmid DNA is intractable, and residual endotoxin in the subsequent rAAV vectors may result in substantial host immune response. Recently, a ClearColi K12 bacterial strain is commercially available, with genetically modified LPS that does not trigger endotoxic response in mammalian cells. Here, we produced rAAV-DJ vectors by plasmids yielded from either DH5α or ClearColi K12 bacterial strains. Our data indicated that the ClearColi K12 strain had satisfactory protection for the rAAV inverted terminal repeat (ITR) sequence. As expected, the ClearColi K12-derived rAAV-DJ vectors had lower endotoxin levels. The physical and biological equivalency of the purified viral stocks were confirmed by electron micrographs, Coomassie blue staining, and transduction assays. Most importantly, the ClearColi K12-derived rAAV-DJ vectors triggered reduced nuclear factor-kappa B (NF-κB) signaling pathway both in cell cultures
