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

backgroundTo evaluate serum homocysteine (Hcy) and small dense low-density lipoprotein cholesterol (sdLDL-C) as predictors of cardiovascular risk in obese patients and their incremental value for prediction models.

methodsA retrospective cohort study was conducted on obese patients. Baseline data and laboratory parameters, including Hcy, sdLDL-C, and traditional cardiovascular risk factors, were collected. Cardiovascular events were recorded during follow-up. Multivariable logistic regression was used to assess the independent associations of Hcy and sdLDL-C with cardiovascular risk. Model performance was assessed using receiver operating characteristic (ROC) curves, calibration plots, and decision curve analysis (DCA).

resultsCardiovascular events were strongly associated with elevated Hcy and sdLDL-C. Hcy levels showed a dose-response relationship with event rates. After adjustment for age, sex, body mass index, smoking status, hypertension, diabetes, conventional lipid profiles, high-sensitivity C-reactive protein, and estimated glomerular filtration rate, serum homocysteine (Hcy) remained independently associated with cardiovascular risk (OR = 1.90, 95% CI: 1.54–2.35, P < 0.001). sdLDL-C also showed significant predictive value (OR = 1.21, 95% CI: 1.13–1.30, P < 0.001). The traditional model’s area under the ROC curve (AUC) was 0.849. Adding Hcy or sdLDL-C individually improved discrimination, while the combined model achieved a significantly higher AUC of 0.972 (95% CI: 0.953–0.991), with superior calibration and clinical net benefit.

conclusionIn obese patients, Hcy and sdLDL-C are independent risk markers for cardiovascular events. Their combined use significantly enhances risk prediction model performance, aiding refined risk stratification.
