Oral treatment with vanadium of Zucker fatty rats activates muscle glycogen synthesis and insulin-stimulated protein phosphatase-1 activity.

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
Since the glucose-lowering effects of vanadium could be related to increased muscle glycogen synthesis, we examined the in vivo effects of vanadium and insulin treatment on glycogen synthase (GS) activation in Zucker fatty rats. The GS fractional activity (GSFA), protein phosphatase-1 (PP1), and glycogen synthase kinase-3 (GSK-3) activity were determined in fatty and lean rats following treatment with bis(maltolato)oxovanadium(IV) (BMOV) for 3 weeks (0.2 mmol/kg/day) administered in drinking water. Skeletal muscle was freeze-clamped before or following an insulin injection (5 U/kg i.v.). In both lean and fatty rats, muscle GSFA was significantly increased at 15 min following insulin stimulation. Vanadium treatment resulted in decreased insulin levels and improved insulin sensitivity in the fatty rats. Interestingly, this treatment stimulated muscle GSFA by 2-fold (p < 0.05) and increased insulin-stimulated PP1 activity by 77% (p < 0.05) in the fatty rats as compared to untreated rats. Insulin resistance, vanadium and insulin in vivo treatment did not affect muscle GSK-3beta activity in either fatty or lean rats. Therefore, an impaired insulin sensitivity in the Zucker fatty rats was improved following vanadium treatment, resulting in an enhanced muscle glucose metabolism through increased GS and insulin-stimulated PPI activity.
