The role of probiotics in modulating the gut microbiota as a potential inhibitor of diabetic kidney disease progression.

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
introductionGut dysbiosis is commonly observed in patients with diabetic kidney disease (DKD) and may contribute to its pathogenesis. Among microbial metabolites, butyrate plays a key role in regulating antioxidant proteins in type 2 diabetes mellitus (T2DM). Based on this, we hypothesized that the administering probiotics to diabetic rats modulates redox status and thereby attenuates renal disease progression.
methodsAn in vivo study was performed using 15 male Wistar rats (8 weeks old, 250-300 g) randomized into three groups (n = 5/group): Control (vehicles: 0.9% saline and 0.1 M citrate, pH 4.2, i.p., on day 1), T2DM (nicotinamide 100 mg/kg, i.p., followed by streptozotocin 60 mg/kg, i.p., in 0.1 M citrate buffer, pH 4.2), and T2DM + Prob (T2DM protocol plus a multistrain probiotic-Bifidobacterium longum, Bifidobacterium bifidum, and Lactobacillus rhamnosus-1010 CFU/mL by gavage for 6 weeks). The parameters evaluated were: serum creatinine, inulin clearance, microalbuminuria, urinary and lipid peroxides, glutathione, and nuclear factor erythroid 2-related factor 2 (Nrf2).
resultsProbiotic treatment significantly increased Nrf2 expression and glutathione levels, reduced urinary and lipid peroxidation, and-beyond attenuating oxidative stress-improved renal function, with lower serum creatinine and microalbuminuria and higher inulin clearance.
conclusionThese findings indicate that probiotics prevented DKD progression, likely by modulating oxidative stress via the gut microbiota. These results suggest that probiotics may serve as renoprotective agents, potentially reducing DKD morbidity in T2DM.
