The association between the expression levels of the five costimulatory molecules and clinical factors. (A) The expression levels of the five costimulatory molecules between the normal and tumor samples; (B) T2 staging vs. T3 and T4 staging; (C) N0 staging vs. N1 staging. (D) Gleason score for 6, 7, 8, 9, and 10. GS represents the Gleason score. The unpaired Student’s t-test was performed for comparison between two samples and the one-way analysis of variance test for comparison between multiple samples.
