Clinical characteristics and burden of COVID-19 in children and adolescents in Colombia: a retrospective database analysis.
Article in BMJ paediatrics open, 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
backgroundThe burden of COVID-19 infections has been extensively studied in some parts of the world. However, in emerging economies and particularly in Latin America and Colombia, research is still incomplete, especially in the paediatric population. This study aims to investigate the burden of COVID-19 infections in children and adolescents in Colombia to understand the burden and outcomes of COVID-19.
methodsThis is a retrospective database analysis of 0-17-year-old persons diagnosed with COVID-19 and given inpatient or outpatient care at a large health maintenance organisation covering 10% of the entire population from March 2020 to January 2023. Cases were confirmed by International Classification of Diseases 10th Revision codes for COVID-19 and a lab test. The incidence rates of COVID-19 cases per 100 000 persons were calculated. With a multivariate logistic regression model adjusted for demographical and clinical characteristics, the factors related to developing severe or critical COVID-19 during the study period were identified.
resultsOf the 76 376 COVID-19 cases included in the analysis, the mean age was 9.8 years, about 51.5% were male, 99.6% lived in urban areas and 98.9% were unvaccinated (76.9% of the cases occurred before the vaccination of this group began on 31 October 2021). Most cases (69 528, 91%) were classified as mild, 0.9% as moderate, 8% as severe and 0.1% as critical. The most prominent comorbidities were mental health-related conditions (18.9%), chronic lung disease (13.6%) and immunocompromised condition (10.6%). 28 deaths were observed, of which 22 had at least 1 comorbidity, the most frequent being chronic lung disease and mental health conditions.
conclusionNearly 1 in 5 cases of COVID-19 was documented in children with underlying medical conditions. Our findings underscore the need to target children with comorbidities.
