Association of the TyG-related indices with hypertension-diabetes comorbidity in middle-aged and older adults: a suburban community-based study.
Article in BMC cardiovascular disorders, 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
backgroundTo investigate the associations between TyG-related indices and hypertension-diabetes comorbidity (HTN-DM) among middle-aged and older adults.
methodsA total of 2854 participants (aged ≥ 45 years) living in a suburban community were included in this study. The collected information comprised three parts: baseline information, physical examination, and laboratory testing. Multivariable logistic regression was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between TyG-related indices (TyG, TyG-BMI, and TyG-BRI) and HTN-DM. Restricted cubic splines (RCS) were used to model the dose-response relationships. Receiver operating characteristic (ROC) curves were applied to evaluate the discriminative performance of these indices.
resultsAmong 2,854 participants, each 1-SD increment in TyG, TyG-BMI, and TyG-BRI conferred multivariable-adjusted ORs (95% CIs) of 3.16(2.75-3.64), 1.39(1.15-1.66), and 1.37(1.22-1.54), respectively (all P < 0.001). Corresponding ORs (95% CIs) comparing the highest versus lowest quartile were 30.99(16.97-62.97), 6.42(4.20-10.14), and 6.43(4.21-10.17), with significant dose-response trends (all P for trend < 0.001). RCS analysis revealed a linear relationship for TyG and nonlinear associations for TyG-BMI and TyG-BRI with HTN-DM. TyG showed the highest observed AUC (0.786) among the evaluated indices, followed by TyG-BMI (0.679) and TyG-BRI (0.633).Across all subgroup analyses, TyG remained consistently and positively associated with HTN-DM prevalence, and the interaction with sex was significant (P = 0.045).
conclusionsThis study revealed that TyG-related indices were associated with HTN-DM. RCS analysis indicated a linear association for TyG but nonlinear associations for TyG-BMI and TyG-BRI. Among the three indices, TyG showed the highest observed AUC. This finding suggests that composite indices incorporating BMI or BRI may not necessarily improve discriminative ability beyond TyG alone.
