Fructo-oligosaccharide attenuates the production of pro-inflammatory cytokines and the activation of JNK/Jun pathway in the lungs of D-galactose-treated Balb/cJ mice.

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
purposeThis study determined the effects of long-term D-galactose (DG) injection on the lung pro-inflammatory and fibrotic status and whether fructo-oligosaccharide (FO) could attenuate such effects.
methodsForty Balb/cJ mice (12 weeks of age) were divided into four groups: control (s.c. saline) (basal diet), DG (s.c. 1.2 g DG/kg body weight) (basal diet), DG + FO (FO diet, 2.5% w/w FO), and DG + E (vitamin E diet, α-tocopherol 0.2% w/w) serving as an antioxidant control group. These animals were killed after 49 day of treatments. Another group of naturally aging (NA) mice without any injection was killed at 64 weeks of age to be an aging control group.
resultsD-galactose treatment, generally similar to NA, increased the lung pro-inflammatory status, as shown in the IL-6 and IL-1β levels and the expression of phospho-Jun and phospho-JNK, and the fibrotic status as shown in the hydroxyproline level compared to the vehicle. FO diminished the DG-induced increases in the lung IL-1β level and expressions of total Jun, phospho-JNK, and attenuated DG effects on lung IL-6 and hydroxyproline, while α-tocopherol exerted anti-inflammatory effects on all parameters determined. FO, as well as α-tocopherol, modulated the large bowel ecology by increasing the fecal bifidobacteria and cecal butyrate levels compared with DG.
conclusionsD-galactose treatment mimicked the lung pro-inflammatory status as shown in the NA mice. FO attenuated the DG-induced lung pro-inflammatory status and down-regulated JNK/Jun pathway in the lung, which could be mediated by the prebiotic effects and metabolic products of FO in the large intestine.
