Note: SE = standard error.
*Initial phase of care = 180 days after diagnosis, terminal phase = 180 days before death, continuing = interval between initial and terminal phases.
†Resource utilization bands categorize patients according to their morbidity and corresponding expected use of health care resources; the bands range from 0 (none) to 5 (highest expected health care costs). See Methods for details.
