Input: Consider Input: Question: Is the risk of uterine rupture increased with single- compared with double-layer closure : a Swedish cohort study?
Answer: There was no significant difference in the rate of uterine rupture when single-layer closure was compared with double -layer closure of the uterus.

Output: no


Input: Consider Input: Question: Does interferon responsiveness change in treatment-experienced hepatitis C subjects : implications for drug development and clinical decisions?
Answer: We contend that P/R-experienced subjects are represented within treatment-naive subjects. There are 2 important implications of this finding: (1) from a drug development perspective, a successful direct antiviral plus P/R therapy (IFN-based triple therapy) trial in P/R-experienced subjects may serve as supportive evidence in treatment-naive subjects; and (2) from a clinical decision perspective, previous P/R exposure should not alter new treatment decisions involving IFN-based triple therapy, as the IFN responsiveness to a second course of IFN is comparable.

Output: no


Input: Consider Input: Question: Are acute myocardial infarction length of stay and hospital mortality associated with language preference?
Answer: Language preference is not associated with AMI mortality, and the small increase in length of stay associated with non-English preference is accounted for by hospital level factors. Our results suggest that system level differences are important to consider in studies of the effect of language barriers in the health care setting.


Output: no
