ATP: Alberta's Tomorrow Project; TP: true positive; excl.: excluding. a A participant had a diagnosis before baseline if their age of first cancer diagnosis in the ACR was before their age at baseline. b Overall TP does not equal common TP plus rare TP. An overall TP reported cancer and had cancer in the ACR, regardless of type. A participant with a common cancer in the ACR had to report a common cancer in order to be a common TP. Similar criterion defines a rare cancer TP.
