TABLE 4.

Association Between Physician Recommendation of CRC Screening Test and Completion of CRC Screening Within Guidelines by Age and Race of the Patient^*

Variable	MD Recommended CRC Screening	CRC Screening Within Guidelines	Unadjusted OR (95% CI) and P Value	Adjusted OR (95% CI) and P Value†
Difference in OR’s Between Age Groups‡			P = .157	P = .192
Age < 65	No	2/28 (7.1%)	20.4 (4.2–99.8)	14.9 (3.7–90.2)
	Yes	22/36 (61.1%)	P < .001	P < .001
Age ≥ 65	No	2/11 (18.2%)	3.7 (0.6–21.6)	3.6 (0.6–22.2)
	Yes	9/20 (45.0%)	P = .148	P = .173
Difference in OR’s Between Race Groups‡			P = .533	P = .555
White	No	2/20 (10.0%)	14.3 (2.8–72.7)	14.1 (2.7–73.0)
	Yes	19/31 (61.3%)	P = .001	P = .002
Non-White	No	2/18 (11.1%)	6.8 (1.2–36.1)	6.8 (1.2–38.2)
	Yes	11/24 (45.8%)	P = .025	P = .029

^*CRC indicates colorectal cancer; OR, odds ratio; CI, confidence interval. OR and P values from logistic regressions of age or race, doctor’s recommendation, and their interaction on CRC screening.

^†Estimates from models adjusting for practice site and race or age.

^‡Significance of interaction between age or race and doctor’s recommendation in each logistic model.
