Abstract
PURPOSE: To evaluate the effects of androgen-deprivation therapy (ADT) on cognitive function in men with nonmetastatic prostate cancer (PC). PATIENTS AND METHODS: The following three groups of men age 50 years or older and matched on age and education were enrolled: patients with PC starting continuous ADT (n = 77), patients with PC not receiving ADT (PC controls, n = 82), and healthy controls (n = 82). A battery of 14 neuropsychological tests, examining eight cognitive domains, was administered at baseline, 6 months, and 12 months. Changes in cognitive scores over time were analyzed using the following three approaches: multivariable linear regression; the proportion of participants per group with 1 standard deviation (SD) or greater declines, and the proportion of participants who declined by at least 1.5 SD on two or more tests. RESULTS: The mean age and education level of participants were 68.9 years (range, 50 to 87 years) and 15.4 years of education (range, 8 to 24 years), respectively. Adjusted for age and education, all three cohorts had similar cognitive scores at baseline other than in one test of working memory. In adjusted regressions, ADT use was not associated with significant changes in the domains of attention/processing speed, verbal fluency, verbal memory, visual memory, or cognitive flexibility at either 6 months (all P > .05) or 12 months (all P > .05). One test each of immediate memory (P = .029), working memory (P = .031), and visuospatial ability (P = .034) were worse among ADT users than controls at 12 months, but these findings were not confirmed using other analytic approaches. CONCLUSION: There is no consistent evidence that 12 months of ADT use has an adverse effect on cognitive function in elderly men with PC.

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
