Although the Kruskal-Wallis test did not return any significant differences in the mean PSA values between individuals with benign disease and those with prostate cancer (χ2=0; p=0.949, Figure 4), statistically significant differences at the alpha level of α=0.05 in the mean ranks of the C⁢D⁢56b⁢r⁢i⁢g⁢h⁢t⁢C⁢D⁢8+ (ID14, p=0.007), C⁢D⁢56+⁢N⁢K⁢p⁢30+ (ID15, p=0.008), C⁢D⁢56+⁢N⁢K⁢p⁢30- (ID16, p=0.031), C⁢D⁢56+⁢N⁢K⁢p⁢46+ (ID17, p=0.023) populations in men with benign prostate disease and those with prostate cancer (Table 3) were observed. The gene discussed is KLK3; the disease is prostate carcinoma.
