Similarly, the median C-reactive protein level tended to be higher in children with severe infection (3.94 mg/dL; IQR: 1.91–5.71 mg/dL) than in children with non-severe infection (2.62 mg/dL; IQR: 0.83–3.71 mg/dL) (P = 0.036; adjusted P = 0.396), as shown in Supplemental Table S3. Here, CRP is linked to infection.
