Therefore, to evaluate the clinical significance of the HMGA1 expression level in lung cancer, HMGA1 expression level was compared with selected clinicopathological features: age, sex, population affinity, smoking status, TNM stage, and nodal involvement separately in lung adenocarcinoma (Figure 12A) and squamous cell carcinoma (Figure 12B) with the usage of the UALCAN database. Here, HMGA1 is linked to lung adenocarcinoma.
