  1. a The normal range of neutrophilia percentage between the age of 6 days to 4 years is 30-35%, that of C-reactive protein is <5mg/L, and that of procalcitonin is<0.25ng/ml.
  2. b Pneumonia was diagnosed when complicated with one of the following conditions: fever; cough; increased breathing rate; moist rales in the lungs, and at the same time satisfying the following condition: chest computed tomography (CT) or X-rays shows infective lesions in the lungs. Severe pneumonia was diagnosed when children with pneumonia complicated with one of the following conditions: conscious disturbance; tachypnea; apnea; oxygen saturation<92%; dehydration; chest computed tomography (CT) and X-rays shows area of lesions >2/3 of one lung, lesions in multiple lobes of two lungs, pleural effusion, pneumothorax, atelectasis, pulmonary necrosis, or pulmonary abscess; or extrapulmonary complications [5].
  3. c Special-grade antibiotics include glycopeptide and carbapenem antibiotics in this study.
