Wendy,

Check out the Mayo Clinic website, it's likely that they'll have what you need.

To: SAS-L@LISTSERV.UGA.EDU cc: Subject: Case and Control Matching

Hello everyone,

Does anyone have SAS code that will perform a one to one (or one to many match) on a group of cases and controls. The key is that once a control is matched to a case, that control should be removed from the list before continuing the match. Meaning -- a control can only be matched once, to a case. Thanks very much for your help,

-Wendy
