Figure 4From: Hypoxia inducible factor 1α gene (HIF-1α) splice variants: potential prognostic biomarkers in breast cancer Kaplan-Meier plot for breast cancer patients illustrating metastasis-free survival according to hypoxia inducible factor 1α ( HIF-1α ) TAG mRNA levels in breast cancer patients (n = 53). Patients with high expression levels of HIF-1α TAGmRNA (median cut-off = 9.95) had a significantly higher risk of relapse (P = 0.01).Back to article page
