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
Diabetic kidney disease (DKD) is a severe complication of diabetes, primarily driven by chronic inflammation, oxidative stress, and gut microbiota dysbiosis. Hydroxysafflor yellow A (HSY), a bioactive compound derived from Carthamus tinctorius L., demonstrates promising renoprotective effects. However, its mechanisms, especially through modulation of the gut-kidney axis, remain poorly understood. This study employed a combination of network pharmacology, a high-fat diet/streptozotocin-induced type 2 diabetic mouse model, 16S rRNA sequencing, and serum metabolomics to explore the therapeutic mechanisms of HSY. Renal function, oxidative stress, inflammation, and gut microbiota composition were evaluated. HSY significantly alleviated renal injury by reducing blood glucose, creatinine, and urea nitrogen levels (p < 0.05), while enhancing renal antioxidant enzyme activity (GSH, SOD, CAT). Inflammatory markers (TNF-α, IL-1β) and AGE-RAGE signaling were suppressed. Analysis of the gut microbiota revealed that HSY enriched SCFA-producing genera (e.g., Lactobacillus, Alloprevotella) and decreased the abundance of Schaedlerella. Serum metabolomics further indicated that HSY modulated riboflavin metabolism, linoleic acid metabolism, and steroid hormone biosynthesis, thereby linking microbial metabolites to renal protection. Spearman correlation analysis revealed strong associations between specific gut microbiota (e.g., Prevotella) and serum metabolites (e.g., eicosapentaenoic acid). HSY mitigates DKD by targeting AGE-RAGE-mediated inflammation, oxidative stress, and gut microbiota dysbiosis while correcting metabolic disturbances. This study offers a novel multi-omics approach to understanding HSY's renoprotective effects, highlighting its potential as a therapeutic agent for DKD.
