Moreover, online Kaplan–Meier survival analysis (http://kmplot.com) showed that patients with higher expression of HOXC8 had significantly lower probability of relapse free survival for lung cancer patients (logrank P = 0.00052), as well as LUAD patients (logrank P = 0.013) and LUSC patients (logrank P = 0.014) (Fig. 1e). Here, HOXC8 is linked to lung cancer.
