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: Consider Input: To determine the impact of the time interval from the end of sperm preparation (TSP) to intrauterine insemination (IUI) on the outcome.', 'Prospective multicentre cohort study.', 'Seven French centers (assisted reproduction group in northeastern France, four academic centers, and three clinics).', 'Eight hundred sixty-two IUI cycles (709 patients) managed by gonadotropins were studied.', 'Cycles were stimulated by either FSH or hMG, and hCG was administrated when the leading follicle diameter measured >15 mm. IUIs were performed 36 hours after ovulation triggering.', 'Generalized linear mixed models for binary outcomes were used to model clinical pregnancy (CP) to assess the effect of TSP adjusted for other predictors (such as maternal age, semen quality, and indication of IUI treatment).', 'The TSP effect was significant, featuring an inverse U-shaped curve admitting an optimum interval of 40-80 minutes improving CP compared with other values. Other significant predictors were total motile spermatozoa inseminated, maternal age, and unexplained infertility.

Output: Is clinical success of intrauterine insemination cycles affected by the sperm preparation time?

Input: Consider Input: The aim of this exploratory study was to identify those factors associated with asthma control assessed according to GINA Guidelines.', '809 (56% female) subjects with asthma were recruited consecutively from both specialist and primary care centres. Asthma control was assessed over a 4-week follow-up period using a composite measure. A multivariate analysis was performed, in which asthma control was included as the dependent variable and several explanatory variables were included as independent variables.', 'Analysis performed on the whole population rendered gender (p=0.003), the type of physician (p<0.001), and age group (p<0.001), as significant factors associated with asthma control. In adults, gender (p=0.001), asthma severity (p<0.001), and type of physician (p<0.001) were significant, and only asthma severity was significant (p=0.043) in children.

Output: Are women , patients with severe asthma , and patients attended by primary care physicians , at higher risk of suffering from poorly controlled asthma?

Input: Consider Input: The aim of this study was to investigate the role of peroxiredoxin 1 (Prdx1) in the invasiveness of pancreatic ductal adenocarcinoma (PDAC) cells.', 'Immunohistochemistry was used to determine overexpression of Prdx1 in human PDAC tissues. Immunoprecipitation and immunocytochemistry were used to determine the interaction and intracellular distribution of Prdx1 and a member of the mitogen-activated protein kinase (MAPK) family protein, p38 MAPK, in PDAC cells. Finally, immunocytochemistry and Matrigel invasion assay were used to examine the effects of Prdx1 and p38 MAPK on the formation of cell protrusions and PDAC cell invasion.', 'Prdx1 is overexpressed in human PDAC tissues. Peroxiredoxin 1 interacts with active forms of p38 MAPK, and complexes of Prdx1 and phosphorylated p38 MAPK localize at the leading edges of migrating PDAC cells. Suppression of Prdx1 decreases active p38 MAPK localized in cell protrusions and inhibits the invasiveness of PDAC cells. Consequently, suppression of Prdx1 inhibits membrane ruffling and protrusions. The p38 MAPK inhibitor SB203580 also decreases the formation of membrane protrusions and inhibits invasiveness.
Output: Does peroxiredoxin 1 promote pancreatic cancer cell invasion by modulating p38 MAPK activity?
