Figure 3. Illustrative. Assessed outcomes plotted on a common standardised axis so that direction and relative magnitude can be compared at a glance. The estimates are not on a common natural scale and the intervals are the Institute's standardised representation of the reported precision, not the published confidence intervals. Published intervals appear in the per-indication extracts and in the text below.

§3.1Hypoactive sexual desire and erectile dysfunction

Anchor outcome. Female Sexual Function Index desire domain.

Effect as recorded. Change in Female Sexual Function Index desire domain of +0.30 versus +0.06 with placebo, and improvement in the Female Sexual Distress Scale item 13 of −0.73 versus −0.41; FSFI-D difference 0.24 (95 % CI 0.14 to 0.34); FSDS-DAO 13 difference −0.32 (95 % CI −0.44 to −0.20).[1,2]

Certainty. Moderate certainty Two identical phase 3 trials with statistically significant but small effects on validated instruments. The Institute reports the effect size on the original scale precisely because the statistical significance and the clinical magnitude diverge here, and readers should be able to see both.

Contributing trials. RECONNECT-301 · RECONNECT-302. Full structured abstracts are published for each.
