“…The overall mortality we observed (26%) is consistent with previous data from cohorts combining infants with medical and surgical NEC (15%-25%), 20,21,25 but the incidence of intestinal strictures is in the lower range reported in the literature (3% vs 4%-30%). 4,20,21,[26][27][28][29][30] The wide range of stricture incidence reported is probably a result of inconsistent definitions leading to ascertainment bias; some studies might report all strictures as diagnosed with radiologic tests, whereas others might report only symptomatic strictures.…”
