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

backgroundSoya supplements are used in the treatment of neuropathic pain. Previous reports reveal that consumption of soy diet before nerve injury prevents the development of neuropathic pain in rats. Biochanin-A, a soy isoflavone, has a naturally occurring inhibitor of fatty acid amide hydrolase (FAAH) that metabolized endocannabinoids.

objectiveThe objective was to evaluate efficacy of biochanin-A in streptozotocin (STZ) induced neuropathic pain in rat model. MATERIALS AND

methodsDiabetes mellitus was induced by an injection of STZ at a dose of 45 mg/kg, i.v. into tail vein of male albino Wistar rats. Biochanin-A was dosed at 0.1, 1 and 5 mg/kg by intraperitoneal (i.p.) administration in diabetic neuropathic rats. Mechanical hyperalgesia and allodynia was measured using Randall-Selitto analgesymeter and manual von Frey filaments of increasing weights respectively. Paw withdrawal threshold (PWT) and percent PWT was determined with respect to both hyperalgesia and allodynia.

resultsTreatment of biochanin-A at three different levels of 0.1, 1 and 5 mg/kg had not significantly altered serum glucose levels throughout the treatment period. In hyperalgesia study, acute treatment with higher dose exhibited 51.1% reversal of paw withdrawal threshold (PWT) while with chronic treatment, efficacy declined to 22.5% reversal of PWT. In allodynia study, acute treatment reversed PWT by 79.4% while with chronic treatment, efficacy was raised to 88.2% reversal of PWT.

conclusionBiochanin-A demonstrated better efficacy in reversing mechanical allodynia than mechanical hyperalgesia. Biochanin-A could be a good drug candidate for further studies to establish the mechanism of attenuation of neuropathic pain.
