  • * Missing data for control (n = 8) and ADT group (n = 4).

  • Missing data for control (n = 9) and ADT group (n = 8).

  • Statistical testing not feasible because of sample size in control group (n = 2; data as mean and range) and ADT group (n = 1).

  • PSA = prostate-specific antigen; GFR = glomerular filtration rate; GnRH = gonadotropin-releasing hormone; CHT = chemotherapy.

  • Qualitative data are number and percentages; continuous data are mean and SD.
