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
objectivesTo investigate the mechanism underlying the inhibitory effect of
methodsEighteen male SD rats were randomized into young group, intraperitoneal D-galactose injection-induced aging group, and BYHWD gavage group. The changes in pulse wave velocity (PWV), vascular SA-β-gal activity, and expressions of p16, p21 and SA‑β‑gal of the rats were examined. Serum exosomes were isolated from the rats, and after characterization using NTA and TEM and for surface markers and vascular cell markers, were examined for miR-590-5p expression using qRT-PCR. The M1/M2 macrophage ratio and cytokine levels were evaluated using immunofluorescence staining and qRT-PCR. Bioinformatics analysis and dual-luciferase reporter assays were carried out to predict the potential target genes of miR-590-5p and validate its targeting relationship with SLC8A3, whose expressions were detected in the vascular tissues of the rats by Western blotting.
resultsCompared with the young rats, the aging rats exhibited significantly increased PWV in the abdominal aorta with elevated vascular expressions of p16, p21 and SA-β-gal, which were all reversed by BYHWD treatment. The isolated serum exosomes were positive for CD63, CD81, CD31 and SM-22, and the exosomes from aging rats showed significantly downregulated expression of miR-590-5p, which was upregulated after BYHWD treatment. The aging rat vessels showed an increased M1/M2 macrophage ratio with elevated M1-specific cytokines and reduced M2-specific cytokines, and BYHWD treatment effectively inhibited M1 polarization of the macrophages. Pearson analysis revealed a negative correlation between exosomal miR-590-5p upregulation and the M1/M2 ratio. Bioinformatics analysis and dual-luciferase assays confirmed that miR-590-5p targets SLC8A3. Western blotting demonstrated increased SLC8A3 expression in aging rat vessels, which was downregulated after BYHWD treatment.
conclusionsBYHWD attenuates vascular aging in rats by modulating macrophage M1 polarization and suppressing vascular inflammation
