This descriptive, retrospective study included neonatal patients admitted to a tertiary hospital's neonatal intensive care unit from January 2013 to December 2016. Data on kidney function were collected from birth to 7 days of life. Patients were stratified into four gestational age groups: below 28 weeks, 28–31 weeks, 32–36 weeks, and term neonates. Qualitative variables were expressed as percentages. Quantitative variables were assessed using the Kruskal–Wallis/Wilcoxon tests. Chi-square analysis was performed for categorical variables. Statistical analysis was conducted using SPSS (Version 22.0), with significance set at p < 0.05.engCreatininaTasa de Filtración GlomerularRecien Nacido Prematurojournal article0.1007/s00467-024-06631-yembargoed accessMortalidad infantilTratamiento médicoGoal 3: Ensure healthy lives and promote well-being for all at all ages
