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
backgroundRenin-angiotensin-aldosterone system activation is the critical factor in renal remodeling and dysfunction. Our previous study suggested that miR-29b may attenuate AngII-induced renal intestinal fibrosis in vitro. In the present study, we aimed to determine whether recombinant rAAV9-mediated miR-29b delivery protects against AngII-induced renal fibrosis and dysfunction.
methodMice were treated with AngII via osmotic mini-pumps, or phosphate-buffered saline. rAAV9 vectors were produced using the rBac-based system in SF9 cells. rAAV9-miR-29b or rAAV9-control-miR was injected into the kidneys of mice subjected to the model of AngII infusion. The role of miR-29b in renal fibrosis was assessed using quantitative polymerase chain reaction, western blot, and histology.
resultsIn AngII-induced fibrotic kidney tissue, miR-29b expression was downregulated. rAAV9-miR-29b delivery significantly reversed renal injury as indicated by decreased serum creatinine and injury related gene expression in AngII-infused mice. Regarding organ remodeling, tubulointerstitial fibrosis and deposition of extracellular matrix components such as collagen type I and type III were significantly decreased in renal tissue from mice delivered rAAV9-miR-29b.
conclusionOur results demonstrate great potential for use of rAAV9 as an applicable vector for delivery of miR-29b as an antifibrogenic factor for treatment of tubulointerstitial fibrosis-induced renal injury.
