LDLRAD3 and non-small cell lung carcinoma: Notably, we confirmed that high expression of LDLRAD3 was correlated with inferior survival using immunohistochemical staining in NSCLC samples (Figures 6D, E); and consistently, uni- and multi-Cox regression demonstrated LDLRAD3 expression as an independent prognostic factor (Figures 6F, G), further supporting the robustness and stability of our RCD-Risk model in NSCLC.
