From: Oncological safety of autologous breast reconstruction after mastectomy for invasive breast cancer

  Hazard Ratio 95% CI p-value
ABR performed 0.82 [0.55–1.22] 0.3301
Age at mastectomy 1.00 [0.98–1.01] 0.5176
Tumour grade 2.56 [1.87–3.51] <.0001*
Invasive tumour size (mm) 1.00 [1.00–1.01] 0.4547
Tumour type ILC 1.17 [0.75–1.82] 0.4920
Tumour type other 0.95 [0.54–1.65] 0.8505
LVI yes 1.66 [1.17–2.35] 0.0047*
LVI unknown 1.72 [1.21–2.44] 0.0026*
Lymph node status positive 2.13 [1.54–2.94] <.0001*
ER/PR positive 0.62 [0.45–0.86] 0.0046*
Her-2 positive 0.77 [0.54–1.10] 0.1537
  1. Factors: HR > 1 (< 1) means higher (lower) risk for patients in the indicated category than reference. Covariates: HR > 1 (< 1) means higher (lower) risk with increasing values of the covariate
