In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Example Input: Context: Helicobater (H.) pylori eradication rates with standard first-line triple therapy have declined to unacceptable levels. To date, amoxicillin-resistant H. pylori strains have rarely been detected. Whether increasing the dosage of amoxicillin in a standard 7 days eradicating regimen may enhance its efficacy is not known. The aim of this paper is to compare the efficacy of a 7 days high-dose amoxicillin based first-line regimen with sequential therapy.', 'We have retrospectively analyzed data from 300 sex and age matched patients, who underwent 3 different therapeutic schemes: (1) standard LCA, lansoprazole 30 mg bid, clarithromycin 500 mg bid and amoxicillin 1000 mg bid for 7 days; (2) high dose LCA (HD-LCA), lansoprazole 30 mg bid, clarithromycin 500 mg bid and amoxicillin 1000 mg tid for 7 days; (3) sequential LACT, lansoprazole 30 mg bid plus amoxicillin 1000 mg bid for 5 days, followed by lansoprazole 30 mg bid, clarithromycin 500 mg bid and tinidazole 500 mg bid for 5 days. Eradication was confirmed by 13C-urea breath test. Compliance and occurrence of adverse effects were also assessed.', 'Eradication rates were: 55% for LCA, 75% for HD-LCA and 73% for LACT. Eradication rates were higher in HD-LCA group compared to LCA (p<0.01), while no significant differences were observed in HD-LCA group compared to LACT (p=ns). Compliance and occurrence of adverse effects were similar among groups.\Question: Is high dose amoxicillin-based first line regimen equivalent to sequential therapy in the eradication of H. pylori infection?
Example Output: High-dose amoxicillin based eradicating treatment is superior to standard triple therapy and equivalent to sequential therapy; compared to the latter, the shorter duration may represent an advantage.

Example Input: Context: "Virtual fracture clinics" have been reported as a safe and effective alternative to the traditional fracture clinic. Robust protocols are used to identify cases that do not require further review, with the remainder triaged to the most appropriate subspecialist at the optimum time for review. The objective of this study was to perform a "top-down" analysis of the cost effectiveness of this virtual fracture clinic pathway.', 'National Health Service financial returns relating to our institution were examined for the time period 2009 to 2014 which spanned the service redesign.', 'The total staffing costs rose by 4% over the time period (from £1 744 933 to £1 811 301) compared with a national increase of 16%. The total outpatient department rate of attendance fell by 15% compared with a national fall of 5%. Had our local costs increased in line with the national average, an excess expenditure of £212 705 would have been required for staffing costs.\Question: Does fracture clinic redesign reduce the cost of outpatient orthopaedic trauma care?
Example Output: The virtual fracture clinic system was associated with less overall use of staff resources in comparison to national cost data. Adoption of this system nationally may have the potential to achieve significant cost savings.Cite this article: P. J. Jenkins.

Example Input: Context: A focal cortical cryogenic brain injury has been reported to reduce the brain pentobarbital concentrations needed to prevent movement in response to pain in rats. This occurred despite any apparent behavioral changes in the awake animals. To determine whether this was true with other anesthetics, the authors determined the minimum alveolar concentration (MAC) for halothane in normothermic, normocarbic ventilated Sprague-Dawley rats previously subjected to a freezing injury of the parietal cortex.', 'Injury was produced in halothane-anesthetized rats by applying a cold (-70 degrees C), 4-mm-diameter brass rod to the exposed dura for 5 or 15 s. Animals then were studied 3 days after injury, a time when cerebral metabolism in the ipsilateral hemisphere reaches a minimum. Minimum alveolar concentration was determined using a tail-clamp stimulus, combined with end-tidal anesthetic sampling. In addition, exploratory activity was measured by the open field test just before MAC determination, and spontaneous nocturnal motility was monitored by an electronic motion sensor during the night before testing.', 'In normal animals subjected only to preparatory surgery, MAC was 1.10 +/- 0.07% (mean +/- SD). Almost identical values were found in rats subjected to 5- and 15-s cryogenic injuries (1.11 +/- 0.07% and 1.08 +/- 0.06%, respectively). There were no intergroup differences in open field test results or in spontaneous nocturnal activity.\Question: Does a focal cryogenic brain lesion reduce the minimum alveolar concentration for halothane in rats?
Example Output:
These results indicate that a focal cortical brain injury that has no obvious neurologic or behavioral effects in the awake rat does not alter halothane requirements.
