Time-Dependent Changes in Effects of Butyrate on Human Gingival Fibroblasts.
Article in Clinical and experimental dental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesButyrate is one of major metabolites of periodontitis-associated bacteria and often detected in periodontal pockets. Butyrate has been considered to affect human gingival fibroblasts (HGFs); however, there was no information on its long-term effect as occurs in periodontitis. Therefore, this study aimed to evaluate the time-dependent effects of butyrate on HGFs. MATERIAL AND
methodsThe effects of butyrate on HGF proliferation, apoptosis, cell morphology, glucose metabolic activity, butyrate metabolic activity, and cell migration ability were evaluated by cell counting, DNA electrophoresis, cell staining, pH-stat system, HPLC, and scratch test, respectively.
resultsHGF proliferation was temporarily inhibited by 5-10 mM butyrate (p < 0.05); however, it resumed at 24 h with morphological changes from spindle to slightly widened (p < 0.05). HGFs cultured with 10 mM butyrate for 12-24 h shifted the glucose metabolic pathway from oxidative phosphorylation to glycolysis (p < 0.05), and increased butyrate consumption, which returned to control levels over 24 h. HGF migration ability tended to decrease at 72 h.
conclusionsHGF cell proliferation and glucose/butyrate metabolism were temporarily inhibited by butyrate and then recovered in a time-dependent manner, accompanied by changes in cell morphology. These time-dependent effects may help to understand the role of butyrate in the pathology of periodontitis.
