Abstract
OBJECTIVE: To estimate the incidence and relative risk of postpartum urinary incontinence in primiparas. METHODS: Over 3 years (1996-1998), healthy nulliparas with no significant history of urinary tract abnormalities were prospectively enrolled. Power analysis indicated that 452 women must complete the study. Participants completed a questionnaire about urinary, fecal, and flatal incontinence. At 6 weeks' and 6 months' postpartum, the same questionnaire was mailed to participants. Statistical analysis consisted of chi-square and Fisher exact tests for nominal variables and analysis of variance and Kruskal-Wallis tests for interval variables. Logistic regression tested independence of variables. RESULTS: A total of 690 primiparas were enrolled in the study and 595 delivered at our hospital: 147 (25%) cesareans, 333 (56%) spontaneous vaginal deliveries, and 115 (19%) instrumental vaginal deliveries. Median birth weight was 3489 g. Urinary incontinence rate at 6 months was 26%. Vaginal delivery was associated with a higher incidence of urinary incontinence (relative risk, 2.8) compared with cesarean. Forceps delivery increased the risk of urinary incontinence (relative risk, 1.5) compared with spontaneous vaginal delivery. There was no significant difference between cesareans done before and during labor. None of the obstetric risk factors were independently significant. CONCLUSION: Cesarean delivery at any stage of labor reduces postpartum urinary incontinence. With multivariable analysis, obstetric risk factors are not significant.

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
