Lipid accumulation product and its association between new onset stroke among middle age and elderly population.
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
backgroundThe lipid accumulation product (LAP), which integrates waist circumference and triglyceride levels, is an effective indicator of excessive fat accumulation. This study aimed to investigate the association between LAP and the risk of incident stroke among adults aged 45 years and older.
methodsUsing data from the China Health and Retirement Longitudinal Study (CHARLS), a total of 9,060 participants aged ≥ 45 years without a prior history of stroke were included. LAP was categorized into quartiles (Q1–Q4). Cox proportional hazards models were applied to evaluate the association between LAP and incident stroke. Model 1 was adjusted for sex, age, and residence, while Model 2 was further adjusted for education level, smoking, alcohol consumption, body mass index, diabetes, hypertension, dyslipidemia, and history of cardiovascular disease.
resultsDuring follow-up, 1,300 incident stroke cases were identified among the 9,060 participants. Cox regression analysis showed that, compared with the lowest LAP quartile, participants in the higher quartile had a significantly increased risk of incident stroke. The association remained robust after excluding participants using lipid-lowering medications in sensitivity analyses. Subgroup analyses demonstrated consistent associations across age, sex, smoking status, alcohol consumption, hypertension, and diabetes. Kaplan–Meier curves across LAP quartiles indicated a significantly higher cumulative incidence of stroke in the high-LAP group.
conclusionsHigher LAP was positively associated with an increased risk of incident stroke among adults aged 45 years and older. LAP may serve as a complementary indicator for stroke risk screening in community populations.
