Predictive value of the atherogenic index of plasma for frailty in older adults.
Article in Internal and emergency medicine, 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
Frailty is a complex syndrome marked by diminished physiological reserves and heightened susceptibility to negative health outcomes. The Atherogenic Index of Plasma (AIP), an indicator of lipid-associated cardiovascular and metabolic risk, has been widely studied in metabolic and cardiometabolic disorders; however, its relationship with frailty remains underexplored. This study seeks to investigate the association between AIP and frailty, as well as evaluate its viability as a predictive biomarker for frailty in older adults. This cross-sectional study encompassed 174 older adults from a geriatrics outpatient clinic. Frailty was evaluated with the Clinical Frailty Scale (CFS) version 2.0, whereas AIP was computed using the formula log(TG/HDL-C). Multivariable logistic regression analysis was conducted to determine independent factors that contribute to frailty. The efficacy of AIP in identifying frailty was assessed by receiver operating characteristic (ROC) curve analysis. Frailty was present in 29.3% (n = 51) of the participants. Logistic regression analysis identified AIP as an independent predictor of frailty (OR: 6.65, 95% CI 1.87-23.64, p = 0.003), along with lower Lawton-Brody Instrumental Activities of Daily Living (IADL) scores and lower Standardized Mini-Mental State Examination (SMMSE) scores. ROC analysis indicated that AIP predicted frailty with an AUC of 0.741 (95% CI 0.669-0.804, p < 0.0001). AIP serves as an independent predictor of frailty, highlighting the significance of lipid metabolism in the pathophysiology of frailty. Due to its significant correlation with dyslipidemia, systemic inflammation, and oxidative stress, AIP may serve as an important biomarker for the early identification of frailty and risk assessment.
