Table 4. CRC screening at six months by GERA risk group.

		Within GERA arm ^*

		Average risk	Elevated risk	Elevated risk vs. Average risk
	N (%)	N (%)	N (%)	Odds Ratio (95% CI)

CRC screening status
Had screening	159 (34.0)	141 (38.1)	18 (26.9)	0.60 (0.33-1.07)
No screening	278 (66.0)	229 (61.9)	49 (73.1)	0.60 (0.33-1.07)

GERA arm participants with unknown GERA risk were excluded, n=77

Screening rates did by not differ within GERA arm (P>0.05, Wald Chi-square test).
