What is Known:
• Community-acquired pneumonia in children is diagnosed based on clinical and radiological definitions.
• Radiological criteria were standardized by WHO-SICR and have been utilized in vaccine studies.
What is New:
• Correlation between the WHO-SICR radiological definitions and clinical and laboratory parameters has not been studied.
• Using the WHO-SICR radiological definitions for alveolar community-acquired pneumonia (CAP) and non-alveolar CAP and the study definition for clinical CAP, it was found that the groups are distinct, differing clinically and in laboratory parameters.
