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
Many complications associated with type 2 diabetes mellitus (T2DM) are closely linked with the generation of reactive species or free radicals leading to oxidative/nitrosative stress. The aim of this study was to investigate the effect of combined administration of metformin with propionate on the degree of oxidative/nitrosative damage in the brain of rats with an experimental model of T2DM. Male Wistar rats were divided into control (healthy rats); rats with T2DM and no further therapy; rats with T2DM that received: metformin, propionate, propionate + metformin. Ventromedial hypothalamus samples were analyzed by transmission electron microscopy, gas-liquid chromatography, Western blotting, RT-PCR and electron paramagnetic resonance. Combined treatment resulted in normalization of the neuronal NOS levels and reduction of mRNA level of induced nitric oxide synthase (NOS) and superoxide radicals compared to untreated T2DM rats. A decrease was also observed in the level of 8-oxyguanine with normalization of fatty acids distribution. The combined treatment partially mitigated ultrastructural alterations resulting from oxidative/nitrosative damage in neurons' mitochondria in T2DM. Thus, we demonstrated a positive effect of the combined use of metformin and propionate on all indicators of oxidative/nitrosative stress in T2DM.
