Association Between Lipid Accumulation Product and Visceral Adiposity Index, as Markers of Visceral Adiposity and Metabolic Dysfunction, and Stroke: NHANES 1999-2018.

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
Aims: Lipid accumulation product (LAP) and visceral adiposity index (VAI) are surrogate markers of visceral adiposity-related endocrine and metabolic dysfunction, including insulin resistance, rather than simple obesity indices. This study aimed to evaluate their associations with stroke prevalence using nationally representative data. Materials and Methods: This cross-sectional study analyzed data from the National Health and Nutrition Examination Survey (NHANES) 1999-2018. Stroke status was determined through standardized questionnaires. LAP and VAI were calculated using established gender-specific formulas. Analyses used the fasting subsample weights with strata and primary sampling units, and missing covariates were multiply imputed. Weighted logistic regression, restricted cubic spline (RCS), subgroup and incremental discrimination analyses were performed. Results: Among 21,146 participants, 721 reported a prior stroke (weighted prevalence 2.64%). Both indices were higher in stroke cases (median LAP 54 vs 42; VAI 1.72 vs 1.46, both Conclusions: Higher LAP and VAI values are associated with a greater prevalence of stroke after adjustment for demographic, socioeconomic, and lifestyle factors, and their attenuation after adjustment for metabolic variables is consistent with partial mediation through insulin resistance and its hemodynamic consequences. Both indices are inexpensive endocrine-metabolic markers of visceral adipose tissue dysfunction and insulin resistance that warrant prospective evaluation.
