CRP and infection: Compared to PSEP, CRP levels were higher at T2 in neonates with shock (median 8.2 mg/dL, IQR 4.2–14.9) and sepsis (median 5.9 mg/dL, 2.2–11.3) compared to those with infection (median 2.6 mg/dL, 1.4–5.5), while PCT was higher at T2 and T4 only in neonates with shock compared to those with infection.
