Development and Validation of a Nomogram for Predicting Chronic Kidney Disease in Older Patients with Type 2 Diabetes Mellitus and Cardiovascular Disease.
Article in Journal of multidisciplinary healthcare, 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
Background: Type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVD) are significant global health challenges, particularly in older adults where their coexistence exacerbates disease burden and leads to adverse outcomes. Chronic kidney disease (CKD), a severe complication of T2DM, is increasing in prevalence and significantly contributes to morbidity and mortality. Early detection of CKD in older patients with T2DM and CVD is crucial for timely intervention. Methods: This study developed a predictive model using electronic health record data from 28,443 older inpatients with T2DM and CVD at the Affiliated Banan Hospital of Chongqing Medical University (2018-2025). The study population was divided into training (n=21,234) and validation (n=7,209) sets. Predictive variables were selected through univariate logistic regression, LASSO regression, and multivariate logistic regression analyses. The model was visualized using a nomogram and validated using ROC curves, calibration curves, and decision curve analysis (DCA). Results: The model identified seven independent predictors of CKD: systolic blood pressure, uric acid (UA), hemoglobin, glycated hemoglobin, white blood cell count, triglyceride glucose, and UA/Cr ratio. The nomogram demonstrated good discriminative ability with AUCs of 0.845 (95% CI: 0.836-0.853) in the training set and 0.853 (95% CI: 0.838-0.867) in the validation set. Calibration curves showed good agreement between predicted and observed risks. DCA indicated that the model provided a net benefit across a range of threshold probabilities, highlighting its clinical utility. Conclusion: The developed nomogram provides a practical tool for clinicians to predict CKD risk in older patients with T2DM and CVD using readily available clinical data. This model can facilitate early identification and intervention for high-risk patients, potentially improving outcomes.
