Furthermore, B cell was reduced with the risk score enhanced, but CD4+ cell and endothelial cell were positively correlated with the risk score (Supplementary Fig. 9D), which indicated that the CD4+ cell immune infiltration might be an opposite effect role in cuproptosis-related prognostic models for CESC patients compared to OC patients. This evidence concerns the gene CD4 and cervical squamous cell carcinoma.
