Epidemiology of participants in a prospective cohort study on pediatric acute kidney injury in South Korea.
Article in Childhood kidney diseases, 2025. 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
Purpose: Acute kidney injury (AKI) is a common and life-threatening complication in hospitalized patients, leading to increased hospital stays and higher mortality rates. In South Korea, prospective studies that comprehensively describe the epidemiology of AKI in this population are lacking. This study aimed to evaluate the demographic characteristics of AKI in children treated at a tertiary care center in South Korea. Methods: This prospective cohort study included children who were diagnosed with AKI at a single tertiary center between February 2016 and July 2021. Results: Of the 781 enrolled patients, 763 were analyzed. The cohort had a mean age of 6.72 years, and 442 patients (57.9%) were male. Hemato-oncologic diseases (202 patients, 26.5%) were the most common underlying condition, followed by preterm infants (128 patients, 16.8%) and kidney disease (108 patients, 14.2%). Nephrotoxic agent exposure (165 patients, 21.6%) represented the leading cause of AKI, followed by infection (135 patients, 17.7%), severe illness (127 patients, 16.6%), and dehydration (121 patients, 15.9%). Patients frequently presented with AKI stage 1 (363 patients, 47.6%). In patients without underlying conditions (96 patients), stage 3 AKI occurred most frequently (40 patients, 41.7%) with a greater tendency for AKI progression (25 patients, 26.0%). However, this group also experienced a higher recovery rate (81 patients, 84.4%). Conclusions: This study offers a comprehensive understanding of pediatric AKI in Korea. These findings highlight the complexity of pediatric AKI and underscore the significance of tailored management strategies based on patient characteristics and AKI etiologies.
