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
Research indicates that patients with salt-sensitive (SS) hypertension experience higher morbidity and target organ damage than in patients with non-SS hypertension. Dysregulated macrophage activation has been implicated in SS hypertension development, with lysine acetylation playing a role in modulating macrophage function. However, the role of macrophage acetylation patterns in SS hypertension remains unclear. This study aimed to investigate how acetylation regulates macrophage function and its role in the pathogenesis of SS hypertension. We employed quantitative acetylation proteomics to characterize the acetylome of bone marrow-derived macrophages in Dahl SS hypertensive rats fed either a high-salt or a low-salt diet. We identified 94 hyperacetylated and 49 hypoacetylated sites on 79 and 45 proteins, respectively, in the high-salt group. Notably, acetylation levels increased at lysine 20 (K20) and K46 on histone H2B, at K56 on H3, and at K77 and K79 on H4c2. We also identified conserved acetylation motifs, analyzed their Gene Ontology terms and pathways, and explored the protein-protein interactions of these differentially acetylated proteins using bioinformatics analyses. Finally, we validated the altered acetylation of H2, H3, H4, and several metabolic proteins using immunoprecipitation and western blotting. Overall, these findings offer insights into the role of lysine acetylation in macrophages from SS hypertensive rats, revealing potential therapeutic targets.
