Association between the intervals on the oral cancer care pathway, stage and diagnosis, and survival.

	Stage at diagnosis		Survival
Association	Significant	Non-significant	Significant	Non-significant
Patient interval	2 studies (31, 56)† (intervals >60 and > 90 days, respectively)	3 studies (32, 46, 54)	Not studied	Not studied
Diagnostic interval	1 study (31)† (intervals >30 days)	3 studies (32, 46, 54)	Not studied	Not studied
Treatment interval	2 studies (40, 55)† (longer intervals and intervals >20 days, respectively)	4 studies (37, 39, 46, 54)	3 studies [37,40,41]†† (intervals >20, >20 and > 45 days, respectively)	2 studies (39, 55)

^†Studies finding a significant positive association (i.e., longer intervals were associated with more advanced stages at diagnosis). ^††Studies finding a significant negative association (i.e., longer intervals were associated with lower survival).
