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

Previous findings of widespread transcriptomic alteration in tissues from connexin null mice raise the issue of whether the transcriptomic changes are directly due to connexin down-regulation or to "compensatory" developmental alterations for the missing gene. To start addressing this question, the authors compared with wild-type control the gene expression profiles of connexin 43 (Cx43) knockout and Cx43siRNA knockdown wild-type cortical astrocytes. Array analysis revealed remarkable parallelism of transcriptomic changes in knockout and knockdown astrocytes, with similarly altered genes being located on all chromosomes and encoding proteins involved in a wide diversity of cell functions. Moreover, gene expression variability was analogously higher in Cx43 null and siRNA-treated astrocytes, and expression interlinkages were similarly altered among a selected subset of genes. This highly significant overlap between transcriptomic alterations in Cx43 knockout and knockdown astrocytes suggests that the widespread changes more likely reflect connexin-dependent Gene Regulatory Networks rather than developmental compensation for the missing gene.
