a
Adjusted for age, education level, and estrogen receptor status; 9 patients were deleted from the analysis due to missing values for tumor size, age, or estrogen receptor status.
b
Adjusted for age; 15 patients were deleted from the analysis due to missing values for tumor grade or age.
c
Adjusted for age; 3 patients were deleted from the analysis due to missing values for age.
