TGIF1 and triple-negative breast carcinoma: Comparing triple-negative breast cancer (TNBC) patients with non-TNBC patients, we found that only in non-TNBC, moderate/strong TGIF expression was significantly associated with a longer DFS (HR 0.76 [95%CI 0.58–1.00]; log-rank p = 0.049; interaction p = 0.427) and we could observe a trend towards a better OS (HR 0.70 [95%CI 0.48–1.01]; log-rank p = 0.056; interaction p = 0.291) (Table 2 and Fig. 5E-F).
