IRF4/FGF23 in gingival crevicular fluid: Diagnostic biomarkers for Dentin Hypersensitivity.
Article in Journal of medical biochemistry, 2026. 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
Background: The aim of this study is to investigate the diagnostic value of interferon regulatory factor 4 (IRF4) and fibroblast growth factor 23 (FGF23) in gingival crevicular fluid (GCF) and serum for dentin hypersensitivity (DH), and to analyze the relationship between IRF4, FGF23 and inflammatory factors and T lymphocyte subsets. Methods: 24 DH patients receiving orthodontic treatment at our institution between 2022 and early 2025 were enrolled as the study cohort, along with 124 healthy controls matched for age and sex. GCF and serum samples were obtained 48 hours post-desensitization therapy to quantify IRF4 and FGF23 levels (via enzyme-linked immunosorbent assay), along with serum inflammatory markers (interleukin [IL]-1β, IL-6, high-sensitivity C-reactive protein [hs-CRP]) and T-cell subpopulations (CD3+, CD4+, CD8+). Statistical analyses included Pearson's correlation to examine relationships between IRF4/FGF23 and clinical parameters, with receiver operating characteristic (ROC) curve analysis determining diagnostic accuracy.
