1 Limited to healthcare visits within 1 year prior to diagnosis of colorectal cancer.
2 Late event is defined as a visit that included treatment-related events (e.g., surgery, palliative care) rather than diagnostic or pre-diagnostic events (e.g., radiology, symptoms). Patients who did not have any colorectal cancer-related healthcare visits are also included in this group.
3 Includes only patients who died on or before March 31, 2009.
