Fig 2: Expression of ALDH3B1 was detected with qRT-PCR and IHC. A, Representative images of ALDH3B1 low and high expression of lung adenocarcinoma. Scale bar: 50 µm. B, Quantitative real-time polymerase chain reaction in 20 pairs of lung adenocarcinoma and normal lungs revealed that ALDH3B1 in lung adenocarcinoma was higher than that in normal lung tissues. ALDH3B1 indicates aldehyde dehydrogenase 3B1; IHC, immunohistochemistry.

Fig 3: Survival curves of different clinicopathological factors after PSM. After PSM, a total of 207 patients were further selected. The overall survival curves of ALDH3B1 (A), tumor size (B), T stage (C), N stage (D), and TNM stage (E) were displayed. ALDH3B1 indicates aldehyde dehydrogenase 3B1; PSM, propensity score matching; TNM, tumor–node–metastasis.
