OR, odds ratio; CI, confidence interval; BCS, breast-conserving surgery; ALND, axillary lymph node dissection; SLNB, sentinel lymph node biopsy; is, in situs; ER, estrogen receptor; LRR, loco-regional recurrence; pT, pathological tumor size stage; is, in situs; PR, progesterone receptor; DFI, disease-free interval.
The bold values mean the difference is statistically significant.
