-
aNumber of samples analyzed; the small differences in numbers of samples in this table compared to Table 3 are due to missing data on ER/PR status
-
bDifference in mean percent methylation (cancer and adjacent) was estimated via linear regression model with generalized estimating equations to account for within-patient covariance
-
cBias corrected, bootstrapped 95 % confidence intervals (CI) were estimated via 1000 bootstrap replications to account for skewed methylation distributions
-
dApproximate p-value estimated from a Wald test of the normal-based bootstrapped estimate over its standard error. P-values > 0.1 are suppressed
-
eThese seven assays were not pursued beyond the pilot phase and therefore have considerably fewer cancer and adjacent tissue samples analyzed
- All estimates of mean percent methylation are adjusted for age, race/ethnicity, stage at diagnosis, tumor grade, and either adjusted for or stratified by ER/PR status
