Note: P-values from comparing across the seven procedure types are <0.001 for all characteristics except for race, which was 0.24 (compared as White vs. non-White). Note that axillary surgery was compared across No, ALND and SLNBx.
All cell values are N (%), except for age and BMI which are mean (SD).
