1 · What the graph read from it

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.

2 · The registry

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

aimThis study aimed to construct and validate a machine learning classifier for cross-sectionally stratifying existing cardiovascular-kidney-metabolic (CKM) syndrome stages using routine composite inflammatory, metabolic and anthropometric indices, and to interpret core driving biomarkers via SHAP analysis. METHODS AND

resultsWe analyzed data from 12,106 participants from the National Health and Nutrition Examination Survey (NHANES). Among 24 initial biomarkers, 10 were selected after addressing multicollinearity and applying feature selection. Several machine learning algorithms were evaluated, with the LightGBM model demonstrating the highest performance (ROC AUC: 0.88). External validation using the China Health and Retirement Longitudinal Study (CHARLS) dataset confirmed the model's generalizability (ROC AUC: 0.84). SHapley Additive exPlanations (SHAP) analysis revealed that metabolic markers-specifically eGDR, METS_VF, TyG, and TyG_BMI-were consistently the strongest predictors across CKM stages, whereas inflammatory indicators showed more limited utility.

conclusionKey metabolic composite indices exhibit significant associations with CKM staging and may serve as practical, clinically feasible tools for risk stratification. The model's robust performance across distinct populations (U.S. and China) supports its potential clinical utility. Further validation in diverse populations and prospective studies is needed to confirm their predictive value and translational potential.
