A RANDOMIZED, DOUBLE-BLIND, PLACEBO CONTROLLED CROSSOVER TRIAL OF NIMODIPINE IN OLDER PERSONS WITH DETRUSOR INSTABILITY AND URGE INCONTINENCE
Bibliographic record
Abstract
PURPOSE: We evaluated the efficacy of nimodipine, a dihydropyridine calcium channel blocker that relaxes vascular and nonvascular smooth muscle, for geriatric urge incontinence. MATERIALS AND METHODS: A randomized, double-blind, placebo controlled crossover trial of 30 mg. nimodipine twice daily for 3 weeks in older persons with detrusor instability and chronic urge incontinence was done. A total of 86 participants with a mean age of 73.4 years were randomized. The primary outcome was the number of incontinent episodes, as measured by the self completion of a 5-day voiding record. Secondary outcomes included the impact of urinary incontinence on quality of life measured with a modified incontinence impact questionnaire (mIIQ) and symptoms, as measured by the American Urological Association (AUA) symptom score. RESULTS: A total of 76 (88.4%) participants completed the study. There was no significant difference in the number of incontinent episodes with nimodipine versus placebo, which included a difference of 0.03 incontinent episodes during a 5-day period (p =0.98, 95% confidence interval -2.7 to 2.8). Scores on the mIIQ and the AUA symptom score were not significantly different with nimodipine versus placebo (p = 0.07 and 0.22, respectively). Regardless of initial treatment, participants had improvement with time, that is a period effect, of incontinent episodes (p <0.0001), mIIQ scores (p = 0.0002) and AUA symptom score values (p <0.0001). CONCLUSIONS: Treatment of geriatric urge incontinence with 30 mg. nimodipine twice daily did not result in a significant improvement of incontinent episodes, mIIQ scores or AUA symptom scores.

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.
