Vardenafil Restores Erectile Function to Normal Range in Men with Erectile Dysfunction
Bibliographic record
Abstract
INTRODUCTION: The ability of oral phosphodiesterase type 5 (PDE5) inhibitor therapy to restore erectile function to normal is an important attribute to men with erectile dysfunction (ED). AIM: To assess the ability of vardenafil to restore normal erectile function in men with general ED. METHODS: In two fixed-dose, parallel-group, double-blind, placebo-controlled, pivotal studies, patients received vardenafil (5, 10, or 20 mg) or placebo for 12/26 weeks. MAIN OUTCOME MEASURE: In this retrospective analysis, the percentage of patients "returning to normal" erectile function at week 12 (as defined by scores > or =26 on erectile function domain of International Index of Erectile Function [IIEF-EF]) was determined, with further stratification by baseline ED severity, etiology, age, and duration of ED. RESULTS: Vardenafil 5, 10, and 20 mg returned 32%, 43%, and 49% of patients, respectively, to normal erectile function after 12 weeks, compared with 10% of patients receiving placebo (P < 0.0001). Return to normal IIEF-EF domain scores was noted irrespective of severity, etiology, age, and duration of ED, and was observed even in challenging-to-treat subgroups. With vardenafil 20 mg, 39% of men with severe ED at baseline, 45-49% of men with ED of mixed or organic etiology, 35% of men aged > or =65 years, and 43% of men with ED of > or =3 years of duration returned to normal erectile function at week 12. Mean per-patient SEP3 (question 3 on the Sexual Encounter Profile) success rates in patients achieving IIEF-EF domain scores > or =26 ranged from 87% to 95%. CONCLUSION: Vardenafil improves the IIEF-EF domain score to the normal range in a substantial proportion of men with ED.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
