Factors associated with overestimation of breast cancer risk

Characteristic	Absolute Risk^a	Comparative Risk^a	Risk Comprehension^a,^b
Characteristic	(n=500)	(n=500)	(n=500)

	OR [95% CI]	OR [95% CI]	OR [95% CI]
Race/ethnicity

Mestizo	0.83 [0.48, 1.42]	1.01 [0.64, 1.61]	0.87 [0.59, 1.29]
Indigenous	1.06 [0.42, 2.68]	1.91 [0.93, 3.93]	0.80 [0.40, 1.60]
Age, years	0.90 [0.84, 0.96]^**	1.01 [0.96, 1.05]	0.99 [0.96, 1.03]
Education, years completed	1.12 [0.89, 1.42]	0.95 [0.77, 1.17]	1.00 [0.84, 1.20]
Breast Cancer Knowledge	0.95 [0.73, 1.23]	0.72 [0.57, 0.91]^**	1.21 [0.99, 1.46]
BCRAT five-year risk	6.95 [3.20, 15.11]^**	0.90 [0.51, 1.59]	n/a

Notes: n/a = not applicable; OR = odds ratio.

All estimates based on multivariate logistic regression adjusted for race/ethnicity, education, age, and breast cancer knowledge;

The logistic model for risk comprehension did not include participants’ BCRAT risk as a covariate, since the risk comprehension estimate includes BCRAT lifetime risk in its calculation;

p<0.05;

^**

p<0.01. All estimates are based on participants who have a valid (non-missing) response to each variable.
