Table 4 Univariate analyses for all cases, and by intrinsic subtype, for the effect of RET expression on overall survival

From: Expression of RET is associated with Oestrogen receptor expression but lacks prognostic significance in breast cancer

RET expression, all cases Hazard Ratio (95% CI) p value
RET positivity 1.02 (0.82–1.26) 0.87
RET positivity, by intrinsic subtype
 Luminal A (ER+and/or PR+, HER2, Ki-67 < 14%) 1.54 (0.79–3.00) 0.21
 Luminal B (HER2-negative) (ER+and/or PR+, HER2, Ki-67 ≥ 14%) 0.99 (0.72–1.36) 0.95
 Luminal B (HER2-positive) (ER+and/or PR+, HER2+) 1.00 (0.52–1.95) 0.99
 HER2 type (ER, PR, HER2+) 1.46 (0.73–2.92) 0.28
 Basal-like (ER, PR, HER2) 0.86 (0.54–1.37) 0.52
RET positivity, by ER status
 ER+ 1.06 (0.82–1.38) 0.65
 ER 1.05 (0.72–1.52) 0.81
