Haglind et al [ 57 ] recently reported data from a multicentre prospective controlled non-randomised study including 778 ORP patients and 1,847 RARP patients; according to patients' IIEF-5 scores, a slightly significant advantage in favour of RARP (odds ratio=0.75; 95% confidence interval=0.58~0.96) was seen at a 12-month postoperative assessment after adjusting for confounding variables.
