IDH1 and breast cancer: Multivariate logistic analysis and plotting of survival curves showed that low IDH1 expression levels were significantly associated with poor DSS (adjusted HR (AHR), 1.57; 95% CI, 1.08–2.30; p = 0.02) but not DFS (AHR, 1.40; 95% CI, 0.93–2.10; p = 0.106) in patients with breast cancer (Table 2).
