Association between atherogenic index of plasma and ICU 28-day mortality in geriatric diabetes: an EICU-based retrospective analysis.
Article in Lipids in health and disease, 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 Atherogenic Index of Plasma (AIP), defined as log10 (triglycerides/high-density lipoprotein cholesterol), is a well-established indicator of adverse metabolic profiles and cardiovascular risk. While its role in chronic cardiovascular disease is established, its prognostic value in acute critical illness among elderly diabetic patients remains underexplored.
methodsThis multicenter retrospective cohort study analyzed data from the eICU Collaborative Research Database (eICU-CRD) across U.S. hospitals (2014–2015). Elderly diabetic patients (≥ 60 years) admitted to the ICU were included (n = 7,873), excluding those with non-first ICU admissions, ICU stays < 48 h, missing AIP components, or incomplete mortality records. Admission AIP values were analyzed. Multivariable-adjusted regression, generalized additive models (GAM), and threshold analyses assessed the AIP–28-day mortality association, with covariate adjustment for demographics, comorbidities, and physiological markers.
resultsAmong 7,873 elderly diabetic ICU patients, 28-day mortality was 4.8% overall, with mortality increasing across AIP tertiles (T1:4.0%, T2:4.5%, T3:6.4%; P < 0.001). Multivariable analysis demonstrated a nonlinear threshold effect at AIP = 0.1: above this threshold, each unit increase conferred 1.9-fold higher mortality risk (95% CI:1.3–2.7, P < 0.001), persisting after full adjustment for physiological/clinical confounders.
conclusionICU admission AIP independently associates with mortality risk in elderly diabetic patients, with a threshold value of 0.1 identifying individuals at heightened risk. These findings implicate atherogenic dyslipidemia in critical illness outcomes. Prospective validation of this threshold and investigation of underlying lipid dysregulation-mortality mechanisms are warranted.
