To further confirm the relationship between NR1H4 expression and immune cell infiltration levels in ccRCC, we used Spearman correlation analysis to explore the correlations between NR1H4 and immune markers of immune cells in TIMER2.0, and the purity-adjusted partial spearman's rho value as the degree of their correlation. The gene discussed is NR1H4; the disease is nonpapillary renal cell carcinoma.
