^aNon-respondents to the willingness question (n = 10 for breast, n = 1 for CRC) were excluded from analyses.

^bVariables associated with willingness in univariable analyses (p<.25) were entered into multivariable models unless highly correlated with other variables. Shaded cells reflect those variables not entered into multivariable models.

^cBreast and CRC sample size was further reduced by 89 and 3, respectively, due to missing values on variables of interest.

^dMissing values ranged from 0 for most variables to 62 for tumor stage.

^eReflects univariable comparisons between breast respondents’ willingness (no, yes) to be contacted and variables of interest.

^fReflects univariable comparisons between CRC respondents’ willingness (no, yes) to be contacted and variables of interest.

^gReflects univariable comparison between willingness (no, yes) to be contacted and cancer type (breast, CRC).

OR, odds ratio; CI, confidence interval.
