Scenarios for various assumptions used in the sample size calculations

Assumptions	All cancers (based on lung cancer)	All cancers	All cancers	All cancers	Restricting to only 90th centile delays	Restricting to only 90th centile delays
Median (days)	14	14	60	60	60	60
Range (days)	0–60	0–100	0–365	0–100	14–100	14–365
N of cancers per step per cluster	9	9	9	9	1	1
Minimum detectable difference (days)	2	5	13	4	9	39
Notes		Allowing greater range		Lower upper value for Primary Care Interval	Minimum set to median of all cancers	Min set to median of all cancers, but increased upper range
