Abstract
AIM: The aim of this article is to evaluate the efficacy and safety of 20-mg tadalafil taken on demand or three times per week and its effect on the sexual activity of patients with diabetes mellitus and erectile dysfunction (ED). METHODS: The scheduled use vs. on-demand regimen evaluation (SURE) was a randomized, crossover, open-label study with 4,262 patients in 14 European countries. The efficacy measures for the 762 patients with diabetes and ED included changes from baseline in the erectile function (EF) domain of the International Index of Erectile Function (IIEF), and the proportion of "yes" responses to patient Sexual Encounter Profile (SEP) questions 2 (SEP2) and 3 (SEP3). The treatment satisfaction was measured with responses to SEP question 4 (SEP4) and SEP question 5 (SEP5), and sexual attempts data were collected. Patient preference for either regimen was determined by the treatment preference question (TPQ). RESULTS: At end point on both regimens, the mean IIEF EF domain score was 22, and >40% of the patients had a normal EF domain score (> or =26). The proportion of "yes" responses was > or =73% for SEP2 (penetration), > or =58% for SEP3 (successful intercourse), >46% for SEP4 (hardness of erection), and > or =45% for SEP5 (overall satisfaction). Efficacy was maintained up to 36 hours post-dosing. More than 70% of sexual attempts while on the three-times-per-week regimen and approximately 50% of the attempts on the on-demand treatment occurred >4 hours post-dosing. Tadalafil was well tolerated, with dyspepsia and headache as the most frequent adverse events reported. Treatment preference was 57.2% for on demand and 42.8% for three times per week. CONCLUSIONS: Tadalafil, when taken on demand or three times per week, is efficacious and safe in men with diabetes and ED.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
