Abstract
BACKGROUND: We determined the prevalence of urethral Mycoplasma genitalium (MG) infection and whether infection was associated with circumcision status among men enrolled in the randomized trial of medical male circumcision to prevent HIV acquisition in Kisumu, Kenya. METHODS: MG and Trichomonas vaginalis were detected in first void urine by APTIMA transcription-mediated amplification assay. first void urine and urethral swabs were assessed for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) by polymerase chain reaction assay. Herpes simplex virus type 2 antibodies were detected by IgG ELISA. Multivariable logistic regression identified factors associated with MG infection. RESULTS: Specimens were collected between July and September 2010, and 52 (9.9%; 95% confidence interval [CI]: 7.3%-12.4%) MG infections were detected among 526 men. N. gonorrhoeae and T. vaginalis were not associated with MG. CT coinfection was 5.8% in MG-infected men, and 0.8% among MG-uninfected men (P = 0.02). MG infection was predominantly asymptomatic (98%). The prevalence of MG was 13.4% in uncircumcised men versus 8.2% in circumcised men (P = 0.06). Being circumcised nearly halved the odds of MG (adjusted odds ratio [aQR] = 0.54; 95% CI: 0.29-0.99), adjusted for other variables significant at the P < 0.05 level: herpes simplex virus type 2 infection (aOR = 2.05; 95% CI: 1.05-4.00), CT infection (aOR = 2.69; 95% CI: 1.44-5.02), and washing the penis ≤1 hour after sex (aOR = 0.47; 95% CI: 0.24-0.95). CONCLUSIONS: MG infection was reduced among men who were circumcised, adding to the benefits of male circumcision in preventing several sexually transmitted infections.

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
