Subjects who reported receiving at least one dose.
Suspected CAP = ICD-10 codes (J12-J86) with a referral for chest x-ray within first 3 days of hospitalization.
Confirmed CAP = Suspected CAP case who had a typical x-ray image of pneumonia (i.e. abnormal pulmonary infiltrates).
Bacterial CAP = Confirmed CAP case with CRP results ≥40 mg/l.
Chest x-ray not done/missing = Suspected CAP case but with chest x-ray not done/missing and unable to be classified further.
N = number of episodes, % = n / Number of episodes with available results x 100.
Above normal (overweight) (≥ +2 Z-score).
Normal weight (≥ −2 to < +2 Z-score).
Moderate underweight (≥ −3 to < −2 Z-score).
Severe underweight (< −3 Z-score).
CAP, community acquired pneumonia; CRP, C-reactive protein, Hib, Haemophilus influenzae type b vaccine; PCV, pneumococcal conjugate vaccines.
