Definition: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: The rs1800255, COL3A1 2209G>A polymorphism in the alpha 1 chain of collagen type III has been associated with an increased risk of pelvic organ prolapse (POP). In one of our previous studies however, polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) misdiagnosed rs1800255, COL3A1 2209G>A in 6% of cases. The high-resolution melting (HRM) analysis on the contrary obtained a 100% accordance for this specific polymorphism and was used in the present study to validate this risk factor for POP.', 'In this case-control study, women with and without symptoms of POP were included and compared. DNA was extracted from blood samples. HRM analysis was used to assess for the presence of the homozygous rs1800255. Groups were compared using the Pearson chi-square, Mann-Whitney, and t tests. The discrepancy between HRM and PCR-RFLP results was investigated using PCR-RFLP results available from our previous study.', 'The study included 354 women: 272 patients with POP and 82 controls; 18 (7%) cases versus 3 (4%) controls had a homozygous rs1800255, COL3A1 2209G>A polymorphism (odds ratio 1.9, 95% confidence interval 0.5-6.9, compared to the wild type), and thus no association between POP and the homozygous polymorphism could be demonstrated. A discrepancy between HRM and PCR-RFLP results was found in 8% of the samples.
Output:
Is collagen type III alpha 1 polymorphism ( rs1800255 , COL3A1 2209 G > A ) assessed with high-resolution melting analysis associated with pelvic organ prolapse in the Dutch population?
