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
objectiveThe objective of this study was to investigate the effects of dietary D-ribose supplementation on the growth performance, nutrient digestibility, serum biochemistry, rumen fermentation characteristics, and microbial LuxS/autoinducer-2 (AI-2) quorum sensing in Hu sheep.
methodsEighteen female Hu sheep, aged 3 months with similar body weights (20.47±0.58 kg), were randomly divided into two groups of nine animals each. The control group was fed a basal diet (CON), while the experimental group received the basal diet supplemented with 300 mg/kg of D-ribose (DR). After 80 days of individual pen feeding, blood, rumen fluid, and fecal samples were collected for analysis.
resultsThe results showed that the average daily gain was higher in the DR group than in the CON group, and the feed-to-gain ratio was lower in the DR group (p<0.05). The apparent digestibility of ether extract tended to be higher in the DR group (p = 0.068). In comparison to the CON group, the levels of serum cortisol, malondialdehyde, and reactive oxygen species were lower in the DR group, while superoxide dismutase and glutathione peroxidase levels were higher, resulting in a decreased oxidative stress index (p<0.05). The rumen pH and microbial protein concentration were higher in the DR group (p<0.05), and no differences in ammonia nitrogen and volatile fatty acids concentrations were observed between the CON and DR groups (p>0.10). The rumen microbial density was higher in the DR group, while the concentrations of AI-2 signaling molecule, biofilm formation, and exopolysaccharides were lower (p<0.05).
conclusionThe findings of this study indicate that dietary supplementation with D-ribose can enhance the growth performance, improve serum antioxidant capacity, and inhibit rumen microbial LuxS/AI-2 quorum sensing in Hu sheep.
