Mortality for colorectal cancer (CRC) during the screening and follow up phases

Group	Individuals enrolled (n)	CRC mortality in screening phase	Individuals followed (n)	CRC mortality in follow up phase
1	2538	1 (0.04)*	2525	11 (0.42)†
2	1010	5 (0.50)	1004	20 (1.99)
1+2	3548	6 (0.17)	3529	31 (0.88)‡
3	1376	3 (0.22)	1369	15 (1.10)

Values are number (%).

*The difference in mortality between the groups during the screening phase was significant (p<0.001).

†Mortality in group 2 was significantly higher than that in groups 1 and 3 (p<0.001 in each case).

‡Mortality in group 1+2 was lower than that in group 3 (p=0.05).
