Single-center analysis of etiology and complications in hospitalized children with chronic kidney disease stages 3-5.

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
Objective: To investigate the etiology spectrum and complication profiles of hospitalized children with chronic kidney disease (CKD) stages 3-5, identify independent risk factors for CKD progression, and provide evidence for optimizing early clinical management. We hypothesized that congenital anomalies of the kidney and urinary tract (CAKUT) are the predominant etiology in this cohort, and baseline eGFR decline plus uncontrolled hypertension would independently predict progression to stage 5 CKD. Methods: A retrospective cohort study was conducted on 170 children with CKD stages 3-5 admitted to the Nephrology Department of Beijing Children's Hospital from January 2016 to December 2023. Etiology, complication rates, and their associations with CKD stages were analyzed. Multivariate logistic regression models were used to identify independent risk factors for progression to stage 5 CKD, adjusting for age, sex, and underlying etiology. Results: CAKUT accounted for 51.8% of cases, followed by glomerular diseases (22.4%). The prevalence of anemia (80.5%), hypertension (64.1%), and CKD-MBD (90.6%) increased significantly with CKD progression ( Conclusion: CAKUT is the leading etiology of CKD stages 3-5 in hospitalized children, with a high burden of complications. Early intervention for anemia, hypertension, and CKD-MBD, combined with enhanced infection prevention, may improve clinical outcomes. Baseline eGFR <30 mL/min/1.73 m² and uncontrolled hypertension are key targets for delaying CKD progression. Notably, the distribution of etiology and complication burden in this cohort parallels patterns reported in North America and Europe, supporting the global applicability of KDIGO-based management strategies.
