Multiple stepwise logistic regression (n = 43) ^a

	Odds ratio	95% CI	P value
Episodes of general anesthesia	0.84	(0.72‐0.98)	.025*
Birth weight	0.30	(0.11‐0.77)	.012*
Age at follow up	1.27	(1.02‐1.58)	.029*

Note: Four patients were excluded from the risk factor analyses. The pulmonary function of one patient could not be evaluated due to incomplete tests, one patient received a tracheostomy and two patients were considered outliers regarding episodes of general anesthesia (27 and 53 episodes).

Abbreviation: CI, confidence interval.

^aThe dependent variable was impaired pulmonary function and the independent variables were: anastomotic leak, episodes of general anesthesia, extubation day, birth weight, age at follow up, and Gross classification.

^*statistical significance.
