Enhanced insulin-hypoglycemic activity in rats consuming a specific glycoprotein extracted from maitake mushroom.

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
aimIntraperitoneal glucose tolerance (ipGTT) and insulin challenge (ICT) tests were implemented to evaluate whether a specific glycoprotein extract of maitake mushroom (Grifola frondosa) known as SX-fraction enhances insulin sensitivity in spontaneously hypertensive rats (SHR).
methodsSHR were divided randomly into a control group, a group receiving the antidiabetic drug, pioglitazone, in their diet, and three groups consuming three different concentrations of SX-Fraction derived from maitake mushroom in their food. The response of circulating glucose and insulin concentrations was examined at different time periods during an ipGTT. The major action of exogenous insulin during the ipGTT occurred within a 15-min period following injection of regular insulin. Accordingly, hypoglycemic activity was evaluated in SHR with and without glucose challenge over a short time frame in the ICT.
resultsEvidence gathered from the ipGTT and ICT tests suggests that the SX-fraction of Maitake in a proper dosage as well as pioglitazone enhance insulin sensitivity. Ingestion of SX-fraction produced a lower-circulating level of glucose after challenge despite no rise in circulating insulin. Compared to control, significantly lower-circulating glucose levels were seen in the groups consuming pioglitazone and higher doses of SX-fraction at 7.5 min after insulin challenge whether or not glucose was given concomitantly.
conclusionSHR in the pioglitazone and SX-fraction groups showed improved glucose tolerance despite no elevation of circulating insulin concentrations and showed enhanced sensitivity to exogenous insulin. Thus, a glycoprotein extract from Maitake mushroom (SX-fraction) should be considered as an alternative method for improving insulin sensitivity.
