Fig 2. Cumulative incidence of infants with elevated CD64 index values during the observation period.

A CD64 index greater than 1.86 was defined as the cut-off value for infection. Day 0 indicates the day of sepsis evaluation (i.e. day of diagnosis). The bars represent the percentage of infants with a positive CD64 index from the beginning of the observation period until the respective day. The differences between groups did not reach statistical significance.
