Association of multiple cholesterol-related indices with diabetic nephropathy: A cross-sectional analysis of the NHANES database.
Article in Science progress. 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
ObjectiveTo investigate the independent associations, dose-response relationships, and heterogeneity across different populations between eight cholesterol-related indices (WHR, LHR, NHR, MHR, PHR, AIP, CHG, and RCII) and diabetic nephropathy (DN), utilizing data from the National Health and Nutrition Examination Survey (NHANES).MethodsThis cross-sectional analysis included 9421 participants from the NHANES 2015-2020 cycles, including 631 DN patients. Multivariable logistic regression was used to assess associations between each index and DN. Restricted cubic spline (RCS) models were employed to explore nonlinear relationships, and effect modification was assessed across subgroups defined by gender, BMI, glycemic control, and other characteristics.ResultsAfter adjusting for multiple confounders, WHR, LHR, NHR, AIP, CHG, and RCII were all significantly positively associated with DN risk (all P < 0.001), with RCS analyses indicating nonlinear "threshold effects" for most indices. Subgroup analyses revealed significant heterogeneity in associations: WHR and LHR showed stronger associations in females; AIP and CHG remained robust across BMI and glycemic control subgroups; RCII showed stronger associations among non-hypertensive and non-smoking individuals.ConclusionIn this cross-sectional study, six cholesterol-inflammation composite indices were independently associated with DN, predominantly exhibiting non-linear dose-response relationships. The variation in association strength across sex, metabolic status, and lifestyle factors suggests a potential pattern of "pathway heterogeneity" in DN risk. These indices warrant further investigation in future studies to explore their value as early clues for risk identification.
