 Flow chart of the study. *Children with fast breathing were categorised as non-severe pneumonia. Fast breathing is defined as ⩾60 breaths per minute for up to 2 months of age, ⩾50 breaths per minute for 2–11 months of age, and ⩾ 40 breaths per minute for 12–59 months of age. †Children with lower chest indrawing were categorised as severe pneumonia, whereas those with danger signs (inability to drink, convulsions, vomiting everything, lethargy or unconscious, severe malnutrition) were categorised as very severe disease. ‡These patients were enrolled and followed up at day 3 and day 5. Day of enrolment was considered as day 0. Information on all the patients who presented with wheeze and were screened for the study, whether they were enrolled or not, were recorded by filling in the screening form. These data were also analysed.
