This study aims to identify the clinical factors that predict the severity of community-acquired pneumonia (CAP) in pediatric patients. Children admitted to Assiut University Children's Hospital with a diagnosis of CAP will be evaluated through clinical examination, vital signs, laboratory investigations, and radiological findings. The study focuses on determining which clinical features are associated with more severe disease, higher need for oxygen therapy, intensive care admission, or complications. Understanding these predictors may help clinicians recognize severe cases earlier and improve patient management and outcomes.
