The average value of PSMA/[creatinine] was slightly higher in the cancer group than in the BPH group in both sediments and EVs (sediments: cancer, 7.36, BPH, 6.03; EVs: cancer, 11.94, BPH, 10.57the), but the differences were not statistically significant because of a wide standard deviation (p > 0.1). The gene discussed is FOLH1; the disease is benign prostatic hyperplasia.
