High triglyceride-glucose index is associated with diabetes mellitus in people with HIV in Southwest China.

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
backgroundThe triglyceride-glucose (TyG) index, an emerging marker of insulin resistance, has shown promise in predicting various noncommunicable diseases. This study investigated the association between the TyG index and the incidence of type 2 diabetes mellitus (T2DM) within a 13-year retrospective longitudinal cohort of people with HIV (PWH).
methodsThis retrospective cohort study utilized data from the China National Free ART Program (CNFAP) in Guangxi, enrolling PWH who initiated ART between 2010 and 2022. The primary exposure, TyG index, was calculated as ln [TG (mg/dl) × FBG (mg/dl)/2]. The outcome, T2DM, was defined as two consecutive FBG measurements at least 7 mmol/l. Gaussian mixture model (GMM)-based multitrajectory analysis identified TyG trajectories. Multivariate Cox proportional hazard models were used to estimate the associations between TyG trajectories and the risk of T2DM.
resultsA total of 15 370 patients were included, with 69.9% men, and a median age of 45 at ART initiation. Over 63 232 person-years of follow-up, 22.7% (3493/15 370) developed T2DM.The 'high Inverted U-shape' TyG trajectory was significantly associated with T2DM [ adjusted hazard ratio (aHR): 2.37, 95% confidence interval (CI): 2.21-2.54]. Additionally, the TyG index outperformed FBG in predicting T2DM at both 5 and 10 years (5-year AUC: 0.640 vs. 0.621, P = 0.003; 10-year AUC: 0.655 vs. 0.592, P < 0.001).
conclusionThis study highlights the clinical value of the TyG index as a predictive marker for T2DM in PWH, suggesting its potential for early risk stratification.
