Nationwide cohort analysis of pediatric urolithiasis: long-term metabolic, renal, and cardiovascular outcomes.
Article in Pediatric nephrology (Berlin, Germany), 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
backgroundPediatric urolithiasis is increasingly recognized not merely as a localized urinary disorder but as part of a systemic metabolic-inflammatory process that may predispose to chronic kidney and cardiovascular disease. However, population-based data in Asian pediatric populations with urolithiasis remain limited. This nationwide study investigated the epidemiologic trends, metabolic risk factors, and systemic outcomes associated with pediatric urolithiasis in Taiwan.
methodsUsing the National Health Insurance Research Database, children newly diagnosed with urolithiasis between January 2009 and December 2019 were identified and matched with controls according to age, sex, and index year. Comorbidities and medication exposures were evaluated, and outcomes including renal, cardiovascular, and metabolic complications were analyzed using Cox proportional hazards models.
resultsAmong 10,113 affected children and 101,130 matched controls, the annual incidence of pediatric urolithiasis declined from 23.85 to 16.22 per 100,000 persons. A male predominance and peak incidence during adolescence were noted. Major associated factors included hypercalciuria (adjusted hazard ratio [aHR] 31.54, with wide confidence intervals), congenital urinary anomalies (aHR 22.58), urinary tract infection (aHR 8.28), and exposure to diuretics or antibiotics. Compared with controls, children with urolithiasis had significantly higher risks of chronic kidney disease (aHR 5.92), hypertension (aHR 1.92), ischemic heart disease (aHR 1.93), and dyslipidemia (aHR 1.83).
conclusionsDespite a modest decline in incidence, pediatric urolithiasis remains a clinically important condition that is associated with an increased risk of long-term renal and cardiovascular morbidity. These findings highlight the importance of early metabolic evaluation, careful medication stewardship, and continued nephrology follow-up to mitigate chronic sequelae.
