Rates of stenosis per clinical response evaluation until 16 months after nCRT in patients without tumour recurrence during active surveillance

	3 months	6 months	9 months	12 months	16 months
Stenosis, easily traversable	15 (11.5)	6 (5.4)	8 (7.8)	7 (7)	7 (7)
dysphagia score, median (i.q.r.); mean(s.d.)	0 (0–11.1); 6.8(9.7)	5.6 (2.8–8.3); 5.6(7.9)	0 (0–2.8); 2.8(5.6)	5.6 (0–11.1); 5.6(6.4)	0 (0–0); 0(0)
Stenosis, traversable with pressure*	1† (1)	3†‡ (3)	0 (0)	0 (0)	0 (0)
Non-traversable stenosis*	0 (0)	0 (0)	1† (1)	1† (1)	1† (1)
Total number of patients§	131	111	102	98	97

Values are n (%) unless otherwise indicated. *No dysphagia scores were available for these patients as they did not participate in questionnaires. †Involves one patient with persistent dysphagia for solid food, but not for semi-solid food and liquids. Dilatation was not performed. ‡Involves one patient who underwent dilatation afterwards. Stenoses that were observed in further follow-up are censored from the table. §Defined as the number of patients with an available endoscopy report corresponding to the particular time point, without development of localized residual tumour within 4 months. i.q.r., interquartile range.
