Development and validation of a nomogram for predicting advanced chronic kidney disease.
Article in iScience, 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
The objective of this study was to develop and validate a nomogram for predicting advanced chronic kidney disease (CKD) through the utilization of routine clinical parameters. To achieve this, we integrated internal and external datasets, employed LASSO and logistic regression to identify independent predictors of advanced CKD for nomogram construction, conducted Bootstrap validation on the training set, and evaluated discrimination, calibration, and net clinical benefit utilizing both internal and external test sets. The results identified six predictors: serum creatinine, age, hematocrit, hypertension, serum ALT, and serum LDH. Furthermore, it was demonstrated that the nomogram exhibited excellent discrimination (AUC: 0.961/0.965/0.939) and good calibration (Brier score: 0.058/0.056/0.073) across the training, internal, and external sets, alongside significant net clinical benefit within the 0-1 threshold. Consequently, it was concluded that this robust and clinically practical nomogram facilitates accurate, individualized predictions of advanced CKD risk, thereby supporting precision kidney disease management.
