 Graphs of surveillance outcomes, including advanced lesion development in the pouch body showing: a maximum adenoma count on record by 5, 10, 15, 20, 25, and 30 years; b contemporaneous adenoma count in the pouch body at the time an advanced lesion was diagnosed in the pouch body for the 39 patients with advanced lesions; c–e Kaplan–Meier curves for time to development of an advanced lesion in the pouch body: c for all patients; d (landmark at end of year 10 since surgery) stratified by presence or absence of an adenoma at the most recent surveillance prior to 10 years (of 104 patients still on study at year 10, 16 subsequently progressed to an advanced lesion; log-rank for differences in survival, P  = 0.002); e (landmark at end of year 10 since surgery) stratified by largest adenoma size observed prior to 10 years (of 104 patients still on study at year 10, 16 subsequently progressed to an advanced lesion; log-rank for differences in survival, P  < 0.001).
