Abstract
We investigated whether there is an association between testosterone levels and prostate cancer aggressiveness in patients treated with radiation therapy who underwent a prostatectomy or prostate radiotherapy (EBRT). A total of 380 patients who received primary or post-operative radiotherapy were identified. At the time of radiotherapy, baseline testosterone levels and body mass index (BMI) measurements were available. On multivariate analysis (MVA), higher prostate-specific antigen (PSA) levels were predictive of testosterone ≥10.4 (OR = 1.3, p = .04) and testosterone ≥12.0 nmol/L (OR = 1.3, p = .04). Patients with a Gleason score ≥8 were more likely to have testosterone <8 nmol/L than patients with a lower score (31% vs. 20%, p = .043). On univariate analysis, a Gleason score ≥8 was associated with a lower likelihood of having a normal (≥8 nmol/L) testosterone level (OR = 0.51, 95% CI: 0.3–0.9, p = .02), and on MVA adjusted for post-surgical versus primary EBRT and BMI (≥30 kg/m2), the Gleason score lost its statistical significance (p = .09). While higher PSA levels are associated with higher testosterone levels, the interaction between Gleason score and testosterone is unclear and merits further study.

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
