Study design and settings
This study is part of a multicenter cohort study from Colombia and
Spain, called EPICO (Epidemiological study of respiratory infections
caused by SARS-CoV-2 infection in pediatric population). This cohort´s
results included data collected between April 2020 and November 2021
from 13 institutions in Colombia (distributed in 5 cities) and 55
institutions in Spain (distributed in 13 provinces). From this cohort, a
subsample of Colombian children was selected to examine the association
between radiology findings (chest x-rays) and clinical presentation,
treatment, and outcomes throughout their hospital course. After
excluding institutions in which remote visualization of chest
radiographs in a PACS (Picture Archiving Communication System) program
was unavailable, a total of 7 hospitals were included. Most of these
hospitals (6 out of 7) were located in Bogotá, and all of them were
private institutions providing fourth level of care.
