NEC incidence of VLBW infants according to GA (weeks). a Incidence of NEC, mNEC, and sNEC in VLBW infants according to GA. The rates of NEC, mNEC, and sNEC decreased as GA increased (NEC: p ≤ 0.001, mNEC: p ≤ 0.001, sNEC: p ≤ 0.001). b Proportion of mNEC and sNEC in VLBW infants between 22 and 31 weeks of GA. Prior to 27 weeks of GA, the ratio of sNEC was higher than that of mNEC, but after 27 weeks of GA, the ratio of mNEC became higher than that of sNEC. GA, gestational age; mNEC, medically treated NEC; sNEC, surgical NEC treated with surgery, or death before surgery with clinical evidence requiring surgery
