Learning disability was added as a covariate to linear regression analysis and a significant correlation between lower BFS and recent episodes of HAEC (p = 0.035) was observed; with LD also a highly significant correlate (p < 0.001).
Logistic regression analysis demonstrated that an impaired PedsQL overall score was independently associated with poor bowel functional outcome (OR 5.1 [1.2–22]; p = 0.029) but the presence of learning disability did not reach statistical significance (OR 4.6 [0.84–26]; p = 0.078), nor did patient sex or extended segment disease.
