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