PGI-I: Patient Global Impression of Improvement; IPSS: International Prostate Symptom Scores; IPSS QoL: IPSS-Quality of Life (QoL), BII - Benign Prostatic Hyperplasia Impact Index; Qmax: peak urine flow rate; n: number of patients; SD: Standard Deviation. Overall and pairwise comparison p-values are from analysis of variance without adjusting for covariates. **: p<0.001.
