Th1/Th17-Treg Imbalance in Asian Atrial Fibrillation: Subtype and Demographic Heterogeneity.
Article in JACC. Asia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundAtrial fibrillation (AF) involves adaptive immune imbalance, particularly within T-cell subsets, yet systematic profiles in Asian cohorts remain limited.
objectivesThe authors aimed to characterize peripheral adaptive immune dysregulation in Asian patients with AF and to examine heterogeneity across AF subtypes and demographics.
methodsIn this case-control study of 173 AF patients and 87 controls, cases were adults with electrocardiogram-confirmed AF recruited from the hospital; controls were participants undergoing routine examinations who were in sinus rhythm and had no structural heart disease. T-cell subsets were quantified by flow cytometry and serum cytokines by enzyme-linked immunosorbent assay. Multivariable logistic models, adjusted for left atrial diameter, left ventricular ejection fraction, and neutrophil-to-lymphocyte ratio, assessed associations of immune indices with AF.
resultsAF was characterized by higher T helper (Th)1 and Th17 cell counts and percentages, with no significant difference in T regulatory cells (Tregs); accordingly, Th1/Treg and Th17/Treg ratios were higher (all P < 0.05). Systemic inflammatory markers (high-sensitivity C-reactive protein, interleukin-6) and effector cytokines (interferon-γ, interleukin-17A) were elevated in AF. In multivariable models, higher Th17 count (OR: 3.30; 95% CI: 1.27-8.53; P = 0.014) and Th1/Treg (OR: 4.20; 95% CI: 1.72-10.24; P = 0.002) were associated with AF. Immune alterations appeared broader in paroxysmal AF, whereas persistent AF showed a more selective Th1/Treg imbalance. Patterns were generally consistent across age, sex, and body mass index strata in exploratory analyses.
conclusionsIn this Asian cohort, AF was associated with an adaptive immune shift toward Th1/Th17 relative to Treg, with subtype-specific patterns. These associations are hypothesis-generating and warrant prospective, tissue-level studies to clarify mechanisms and clinical relevance.
