Task: Answer Verification
Input (English): Question: Are estrogen and other female reproductive risk factors strongly associated with the development of rheumatoid arthritis in elderly women?
Answer: Few reproductive factors showed a strong or statistically significant association with RA in elderly women. The association of polycystic ovary syndrome may be indicative of perturbations of endocrine-immune activity that may influence the development of RA. This prospective cohort study adds to the understanding of the potential contribution of hormonal factors to the cause of RA in older women.
