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

Because inhibitors of advanced glycation end-products (AGEs), for example pyridoxamine, significantly inhibit the development of retinopathy and neuropathy in rats with streptozotocin-induced diabetes, treatment with AGE inhibitors is believed to be a potential strategy for the prevention of lifestyle-related diseases such as diabetic complications. In the present study, the MeOH extract of Epimedii Herba (EH; aerial parts of Epimedium spp.) was found to inhibit the formation of N (ε) -(carboxymethyl)lysine (CML) and N (ω) -(carboxymethyl)arginine (CMA) during incubation of collagen-derived gelatin with ribose. Furthermore, compounds with inhibitory effects against CML and CMA formation were isolated from EH. Two new prenylflavonoids (compounds 1 and 2) and two known compounds (3 and 4) were found to significantly inhibit the formation of both CML and CMA; compound 4 (epimedokoreanin B) had the strongest inhibitory effect of the isolated compounds. These data suggest that epimedokoreanin B could prevent clinical complications of diabetes by inhibiting AGEs.
