Figure 2:

Kaplan-Meier estimated plot showing probability of surgery-free survival in relation to time after index dilatation in patients with anastomotic or F strictures (p = 0.86). This analysis is restricted to 83 patients having repeated dilatations only for strictures causing symptoms of bowel obstruction.
