Background: Although the WHO standard for paediatric radiological pneumonia has been useful
in vaccine trials, it lacks sensitivity for some significant pneumonic lesions and inter-observer
agreement may be limited. We assessed inter-observer variation in interpretation of WHO

Methods: Four clinicians were trained using the first 122/222 WHO classified radiographs. The
remaining radiographs were used to assess agreement between clinicians and WHO. The
alternative standard used WHO definitions for quality, other infiltrate and pleural effusion, while
the alveolar infiltrate category (end-point consolidation, EPC) was separated into two categories:
EPC-A (alveolar infiltrate spanning 2 intercostal spaces), and EPC-B (alveolar infiltrate spanning
