AISI and MASLD: a nonlinear association in U.S. adults (NHANES 2017-2020).
Article in BMC gastroenterology, 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
backgroundSystemic inflammation is recognized as a key driver in the development of metabolic dysfunction-associated steatotic liver disease (MASLD). While emerging evidence suggests that the Aggregate Index of Systemic Inflammation (AISI) may reflect overall inflammatory burden, its association with MASLD prevalence remains poorly understood, especially in large population-based studies.
methodsThis is a population-based, cross-sectional study analyzed NHANES data (2017-2020) from 5,948 U.S. adults aged ≥20 years, including both sexes and diverse ethnicities. We aimed to assess the association between the Aggregate Index of Systemic Inflammation (AISI) and MASLD prevalence. MASLD was defined by a controlled attenuation parameter (CAP) ≥274 dB/m, and participants with viral hepatitis or excessive alcohol intake were excluded. AISI was calculated from neutrophil, monocyte, platelet, and lymphocyte counts. We used adjusted analysis models to evaluate the association, adjusting for demographic and clinical covariates. Subgroup and sensitivity analyses were conducted to test the robustness of our findings.
resultsOur research identified a significant association between AISI and MASLD prevalence. After adjusting for confounders, individuals in the highest AISI quartile had a 53% higher risk of MASLD (OR = 1.53; 95% CI: 1.14-2.06; P for trend < 0.001). A nonlinear relationship was observed, with an inflection point at [Formula: see text] AISI = 8.552.
conclusionAISI is independently associated with MASLD prevalence in U.S. adults and may serve as an accessible biomarker for MASLD risk stratification in primary care settings.
