Development of a prognostic nomogram for long-term renal function in chronic kidney disease patients on the basis of clinicopathologic parameters.
Article in Clinical and experimental nephrology, 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 AND
objectivesTo investigate the factors influencing the occurrence of intermediate and long-term renal failure in patients with chronic kidney disease (CKD), to construct a risk prediction model, and to provide a reference for the timing of substitution therapy in these patients.
methodsA total of 354 patients who attended the Nephrology Department of Guizhou Medical University Hospital from January 2018 to July 2019 were used as the training set. The variables were screened using methods such as LASSO regression and the model was visualized using a nomogram. A total of 139 patients who attended the Department of Nephrology of the First People's Hospital of Bijie between November 2018 and June 2021 were used as an external validation cohort, and analyses were performed to verify the judgmental ability and clinical utility of the model.
resultsMultifactorial Cox regression analysis revealed that hypertension, mesangial proliferation, renal tubular atrophy, serum potassium, and estimated glomerular filtration rate were independent risk factors for renal failure. The 1-year AUC values of internal validation and external validation were 0.978 (0.970-0.984) and 0.919 (0.853-0.986), respectively. The 2-year AUCs were 0.945 (0.914-0.961) and 0.902 (0.822-0.982), respectively. The AUC values over three years were 0.933 (0.897-0.945) and 0.915 (0.846-0.985), respectively. The bias correction curves were close to the ideal curves and revealed a high degree of consistency between actual observations and predictions.
conclusionWe have developed a nomogram with excellent predictive power regarding the likelihood and time to progression to end-stage renal disease in CKD patients at 1, 2, and 3 years, which may help to classify patients and select the appropriate treatment plan in advance.
