The mean change in DPSIQ for tadalafil was 1.6, which represents a shift from 'very difficult' to 'moderately' or 'slightly difficult' sexual performance vs. a mean change of 0.4 in the placebo group (p < 0.0001). Among men receiving tadalafil with an International Index of Erectile Function–Erectile Function (IIEF–EF) end‐point score of ≥ 26 or who achieved a minimal clinically important difference in IIEF–EF score at end‐point, the mean changes in CPSIQ were 3.0 and 2.4, respectively (both p < 0.0001).</p> </sec> <sec id="ijcp12406-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Once‐daily tadalafil vs. placebo improves confidence and decreases difficulty in performing sexual intercourse for men with ED who were incomplete responders to as‐needed PDE5 inhibitor therapy.</p> </sec> </abstract>
