Figure. Adherence to NCCN-Recommended Surveillance Schedule.

In each interval, the bar on the left indicates the number of expected visits, assuming all patients followed for the full interval were adherent to NCCN guidelines. The bar on the right reflects the number of patients meeting the minimum number of visits needed to be considered adherent. Patients were followed until their first recurrence or until death or loss to follow-up. To have been counted in an interval, a patient must have been followed (without censoring, recurrence, or death) for the full interval. NCCN indicates National Comprehensive Cancer Network.
