question:
Question: Is assessment of joint space narrowing with conventional standing antero-posterior radiographs : relief in mild-to-moderate pain a confounder in recent osteoarthritis structure-modifying drug trials?
Answer: Knee pain relief did not bias the report of a structure-modifying effect of glucosamine sulfate in two recent long-term trials, possibly due to the mild-to-moderate patient characteristics. Consensus deliverables should acknowledge that the potential limitations of conventional standing antero-posterior radiographs should not be overestimated since they may not apply to all patient populations and to all studies using this gold standard technique.
answer:
no


question:
Question: Does surfactant replacement therapy on ECMO improve outcome in neonates with congenital diaphragmatic hernia?
Answer: The data from this study suggest that surfactant replacement on ECMO for neonates with congenital diaphragmatic hernia does not provide significant benefit in the infant's clinical course with respect to survival, length of ECMO course, length of intubation, or subsequent need for supplemental oxygen.
answer:
no


question:
Question: Does ondansetron prevent pruritus induced by low-dose intrathecal fentanyl?
