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.

[EX Q]: 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?
[EX A]: 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.

[EX Q]: Context: To describe a novel form of pontocerebellar hypoplasia (PCH) and map its genetic locus.', 'PCH is a heterogeneous group of disorders that are characterized by abnormally small cerebellum and brainstem. Autosomal recessive inheritance has been implied in many cases, but no genetic loci have been mapped to date.', 'The authors studied a consanguineous family from the Sultanate of Oman with three siblings with a novel form of PCH. The authors performed clinical studies and linkage analysis of this pedigree.', 'The clinical features of the affected children include developmental delay, progressive microcephaly with brachycephaly, seizures during the first year of life, hypotonia with hyperreflexia, short stature, and optic atrophy. Imaging studies showed a small pons and cerebellum, prominent sulci and lateral ventricles, and decreased cerebral white matter volume. A lack of dyskinesias distinguishes this pedigree from PCH type 2. Genetic studies of this family revealed evidence of significant linkage to chromosome 7q11-21 (maximum multipoint lod score 3.23).\Question: Does a novel form of pontocerebellar hypoplasia map to chromosome 7q11-21?
[EX A]: This pedigree represents a novel form of autosomal recessive PCH, which the authors propose to call cerebellar atrophy with progressive microcephaly (CLAM). This disorder maps to chromosome 7q11-21, and this locus was named CLAM. This report represents the first identification of a genetic locus for PCH.

[EX Q]: Context: The purpose of the present study was to investigate the relationships between blood pressure (BP), insulin resistance as determined by a homeostasis model (HOMA-IR), and body fat distribution.', 'Anthropometric indices of adiposity, metabolic variables (fasting serum insulin and a homeostasis model assessment [HOMA] index of insulin sensitivity), BP and several cardiovascular risk factors were measured during a cross sectional survey of 53477 apparently healthy Korean subjects who requested a health status check. Hypertension was defined as a systolic BP > or = 140 mmHg or a diastolic BP > or = 90 mmHg and we excluded the subjects taking BP-lowering medication.', 'Systolic and diastolic blood pressure (SBP, DBP) were positively and significantly associated with age, body mass index, waist circumference, and waist/hip ratio. In addition, SBP and DBP were positively associated with fasting serum insulin levels and the HOMA index. By multiple regression analysis age, waist circumference, body mass index, HOMA index and female sex were independently associated with either increased SBP or DBP. When the population is divided into quintiles according to insulin resistance (measured by HOMA analysis) prevalence of hypertension in the second, third, fourth and fifth quintiles compared to subjects in the first quintile are 1.004(95% CI 0.875-1.152, p = 0.957), 1.200(95% CI 1.052-1.369, p = 0.007), 1.312(95% CI 1.151-1.494 p < 0.001 ), and 1.603(95% CI 1.408-1.825 p < 0.001). In addition age, sex, body mass index and waist circumference were found to be significantly associated with hypertension.\Question: Are insulin resistance , body mass index , waist circumference independent risk factor for high blood pressure?
[EX A]:
Our results showed that insulin resistance, body mass index and waist circumference are independent risk factors of a high BP in Koreans.
