3.1. Study Participants. During the study period, we enrolled
420 (27.2%) children with severe pneumonia out of a total
of 1517 under-five admissions. There was a slight male
preponderance (male to female ratio was 1.2 : 1), 168 (40%)
were infants, and mean (SD) age of the recruited patients was
18.0 (13.7) months (Table 1).
