Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Example Input: Although the majority of evidence does not support association between Helicobacter pylori infection and ischaemic heart disease, the nature of this relationship may differ when virulence of the infecting strains are examined.', 'The prevalence of IgG antibody evidence of infection with CagA positive stains of H. pylori was investigated in stored plasma samples from 259 cases of myocardial infarction (aged 25-70 years, 74 males) and 259 population based controls from the same area in Northern Ireland. Two-hundred and seventy (52.1%) subjects were seropositive for anti-CagA IgG. CagA seropositivity was more common in cases than in controls: 56.4 vs 47.9%, odds ratio for seropositivity in cases (95% CI) 1.41 (1.00, 1.99). Substantial attenuation of this relationship occurred on adjustment for age, sex, number of siblings, smoking and measures of socio-economic status: odds ratio (95% CI) 1.16 (0.79, 1.70). A similar pattern was seen for seropositivity for all H. pylori strains.

Example Input: Whether moderate to severe obesity (body mass index (BMI)≥30 to <40kg/m(2)) contributes to breast cancer recurrence and mortality remains uncertain.', '1199 women, recruited within 12 months of their diagnosis of hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) invasive breast cancer completed an enrolment questionnaire and an annual follow-up questionnaire every 12 months for another 5 years. The impact of obesity on time to either local or distant recurrence or new breast cancer, or death due to breast cancer was determined by Cox regression. Women in the most extreme categories of BMI (<18.5 and ≥40) were excluded from the analysis.', 'Of the 1155 included women, mean age, 58.4±11.6 years, 53.8% had Stage 1 disease and 88.9% received oral adjuvant endocrine therapy (OAET) within 2 years of diagnosis. The likelihood of an event was significantly associated with moderate to severe obesity (HR=1.71, 95%CI, 1.12-2.62, p=0.014), disease beyond Stage 1 (HR=2.87, 95% CI 1.73-4.75, p<0.001), OAET (HR=0.26, 95%CI 0.14-0.46, p<0.001), mastectomy (HR=3.28, 95%CI 1.98-5.44, p<0.001) and radiotherapy (HR=2.12, 95%CI 1.24-3.63, p=0.006). For Stage 1 disease, only moderate to severe obesity (HR 3.23, 95%CI 1.48-7.03, p=0.003) and OAET use (HR 0.41, 95%CI 0.17-0.98, p=0.046) were significantly associated with an event.

Example Input: Laparoscopic splenectomy has been increasingly used in patients with idiopathic thrombocytopenic purpura. Because it is associated with minimal abdominal trauma, platelet consumption could be reduced with the laparoscopic approach. The aim of this study was to analyze intraoperative bleeding and the need for apheresis platelets, comparing laparoscopic with open splenectomy.', 'Records of 40 patients who underwent splenectomy (20 through laparoscopy and 20 through open surgery) for idiopathic thrombocytopenic purpura were retrospectively reviewed. Intraoperative bleeding and need of perioperative apheresis platelets were evaluated in both groups. Statistical evaluation was conducted using the Mann-Whitney rank test, and differences were considered significant at P<0.01.', 'The mean amount of intraoperative bleeding was less in the laparoscopic group (P<0.01). Apheresis platelets were necessary in all patients in the open group (2 units transfused in 55% and 1 unit in 45% of cases) and only in 30% of cases in the laparoscopic group (1 unit transfused in each case).
