Figure 2.

Data from 1089 very low birth weight infants at Emory University Hospital Midtown from 2008 through 2020. The annotated statistical process control chart shows 3 sigma control limits (red dotted line) along with the mean incidence of NEC (solid green line), with individual data points (blue boxes) showing quarterly incidence. The goal denotes a target NEC incidence of < 5%. There was a reduction in the incidence of NEC from 13.2% to 5.6%, meeting special cause rules.
