Similarly, the univariate Cox regression analysis of DSS outcomes indicated that high OLR1 expression was a risk factor for DSS in patients with ACC, COAD, ESCA, HNSCC, LGG, LUSC, PAAD, and UCEC; however, the opposite result was observed in CHOL, KIRP, LUAD, PCPG, and SKCM (Figure S1B). This evidence concerns the gene OLR1 and head and neck squamous cell carcinoma.
