Improvement in BPH symptoms from baseline following water vapor thermal therapy reported in standardized MCID units with 95% CI. The MCID is −3.0 for IPSS,[12] −0.5 for IPSS-QOL,[12] −0.5 for BPHII,[12] and 2 mL/s for Qmax.[14] Treatment effects below 0.5 MCID units indicate that it is unlikely that an appreciable number of patients will show a clinically important benefit, treatment effects between 0.5 and 1 MCID units indicate that a treatment may be beneficial to an appreciable number of patients, and treatment effects above 1 MCID unit indicate that many patients may gain important benefits from treatment.[15,16] BPH = benign prostatic hyperplasia, BPHII = benign prostatic hyperplasia impact index, CI = confidence interval, IPSS = international prostate severity score, IPSS QOL = International prostate severity score quality of life, MCID = minimal clinically important difference, Qmax = maximum flow rate.
