Abstract
OBJECTIVE: To examine reproductive outcomes among flight crew. METHODS: Ten thousand two hundred five flight crew members and a control group of 2118 air traffic control officers completed a questionnaire in 2001 to 2004, United Kingdom. RESULTS: Similar proportions of flight crew and air traffic control officers reported having ever had difficulties in conceiving a baby. Risks of miscarriages and congenital malformations among pregnancies fathered by men who did not differ by occupation, but stillbirth risk was higher among flight crew (odds ratio = 2.85; 95% CI = 1.30-6.23). Among pregnancies reported by women, risks of miscarriage and stillbirth did not differ by occupation but risk of congenital malformations was higher among flight crew (odds ratio = 2.37; 95% CI = 0.43-13.06). CONCLUSIONS: Flight crew-related exposures were not associated with adverse reproductive outcomes except for possible links, based on small numbers, between paternal exposure and stillbirths and maternal exposure and congenital malformations.

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
