Furthermore, univariate analyses on clinical outcome of the lung cancer patients let us to identify that oncological metastasis is significatively (P ≤ 0.009) associated with overexpressed LncRNA SOX2‐OT levels (Table S4), as well as, overexpressed SOX2 levels significatively (P ≤ 0.021) associated with smoking exposition (Table S5). This evidence concerns the gene SOX2 and lung cancer.
