Kaplan–Meier analysis of low versus high Gal-3 expression revealed that low Gal-3 expression level was significantly correlated with poorer RFS (log-rank p = 0.048) and potentially with OS (log-rank p = 0.051) in T1 lung adenocarcinoma (Figure 3A). The gene discussed is LGALS3; the disease is lung adenocarcinoma.
