Clinical characteristics of research subjects.

Characteristics	Naïve controls (n = 19)		Full-term patients	Pre-term patients
	T1-weighted (n = 17)	T2-weighted (n = 13)	Both scans (n = 13)	Both scans (n = 13)
Sex (male), n (%)	15 (88%)	12 (92%)	7 (54%)	8 (62%)
Average GA at birth (weeks) (SD)	39.5 (0.9)	39.6 (1.0)	38.5 (1.1)	32.2 (2.9)
Median CA at scan [range] (months)	3.2 [0.4–12.3]	2.8 [0.4–7.1]	4.7 [0.6–13.0]	3.8 [1.4–7.5]
Multiple births, n (%)	1 (6%)	1 (8%)	1 (8%)	2 (15%)
INCIDENCE OF MAJOR DIAGNOSES:
Isolated LGEA, n (%)	0	0	3 (23%)	3 (23%)
LGEA with TEF, n (%)	0	0	5 (38%)	9 (69%)
Other, n (%)	0	0	5 (38%)	1 (8%)

This table summarizes clinical characteristics of all subjects included in the quantitative (T1- and T2-weighted) analyses. Patients were stratified into clinical groups of non-cardiac congenital anomalies: (1) isolated LGEA, (2) LGEA with TEF, and (3) other (included LGEA as part of VACTERL association (without cardiac involvement) and/or necrotizing enterocolitis). GA, gestational age; CA, corrected age; LGEA, long-gap esophageal atresia; TEF, tracheo-esophageal fistula; VACTERL stands for vertebral defects, anal atresia, cardiac defects, tracheo-esophageal fistula, renal anomalies, and limb abnormalities.
