Groups 2

Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.

Group	Title	Description	With the outcome	Analysed	ClinicalTrials.gov code	Source
Group 1	Preoperative Geriatric Consult or Assessment	Patients who have a geriatric assessment of consult billed in the 4 months before surgery~Preoperative geriatric consult or assessment: A preoperative geriatric consult or assessment will be considered to be present if such a consult or assessment is billed by a geriatrician for a patient in the cohort within 4 months preceding surgery. For the primary analysis we will collapse both geriatric consultations and comprehensive geriatric assessments into a single exposure level.	103	7,352	EG000	ClinicalTrials.gov
