VIM and non-small cell lung carcinoma: The scatter plot of OPN, E‐cadherin, and vimentin protein expression revealed a significant negative correlation between OPN and E‐cadherin in NSCLC tissues (r = −0.636, p = .003; Figure 4E,F,H) and a positive correlation between OPN and vimentin protein levels (r = 0.51, p = .021; Figure 4E,G,I).
