Association between triglyceride glucose (TyG)-atherogenic index of plasma (AIP) index and new-onset stroke risk in middle-aged and older Chinese individuals: a nationwide prospective cohort study.
Article in BMC neurology, 2025. 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
backgroundThe triglyceride-glucose (TyG) index serves as an established indicator of insulin resistance, while the atherogenic index of plasma (AIP) functions as a reliable marker for dyslipidemia. Nevertheless, the synergistic impact of the combined TyG-AIP index on cerebrovascular events remains insufficiently understood. This investigation explored the relationships between longitudinal variations in the TyG-AIP index and cumulative exposure, baseline characteristics, as well as incident stroke risk among Chinese middle-aged and elderly populations.
methodsThe analysis encompassed 6,987 participants aged 45 years and above from the China Health and Retirement Longitudinal Study (CHARLS), with emphasis on initial TyG-AIP measurements (2011), follow-up TyG-AIP values in 2015, and aggregate TyG-AIP scores calculated from these assessments. The temporal variations of the TyG-AIP index were categorized into three distinct groups through K-means cluster methodology. Logistic regression approaches were utilized to explore the association between TyG-AIP index levels and incident cerebrovascular events. Restricted cubic spline (RCS) analysis was implemented to evaluate potential non-linear associations, whereas receiver operating characteristic (ROC) analysis determined the discriminative performance.
resultsThroughout the 5-year observation period (2015 to 2020), cerebrovascular events occurred in 340 participants (4.87%). The stroke occurrence rates across Clusters 1, 2, and 3 were 5.96%, 3.87%, and 5.52%, respectively. Following adjustment for potential confounders, Cluster 1 characterized by moderate and declining TyG-AIP values (OR = 1.471, 95% CI 1.030–2.100) and Cluster 3 featuring elevated and ascending TyG-AIP levels (OR = 1.604, 95% CI 1.204–2.137) both demonstrated heightened risk for incident cerebrovascular events relative to Cluster 2. The third quartile group exhibiting high aggregate TyG-AIP values (OR = 1.393, 95% CI 1.038–1.869) and the third quartile group with elevated initial TyG-AIP levels (OR = 1.396, 95% CI 1.052–1.854) were similarly linked to augmented stroke risk. The RCS examination indicated a non-linear association between aggregate TyG-AIP values and cerebrovascular risk (P for non-linearity = 0.047). ROC evaluation revealed that the TyG-AIP index possessed enhanced discriminative capacity relative to standalone TyG or AIP parameters.
conclusionsTemporal variations in initial and aggregate TyG-AIP values demonstrate independent associations with heightened cerebrovascular risk among Chinese middle-aged and elderly populations. The TyG-AIP index shows a nonlinear association with stroke risk and is anticipated to be a more efficient and significant indicator for evaluating early stroke risk compared to individual metabolic indices.
