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: Anxiety disorders increase risk of future cardiovascular disease (CVD) and mortality, even after controlling for confounds including smoking, lifestyle, and socioeconomic status, and irrespective of a history of medical disorders. While impaired vagal function, indicated by reductions in heart rate variability (HRV), may be one mechanism linking anxiety disorders to CVD, prior studies have reported inconsistent findings highlighting the need for meta-analysis.', 'Studies comparing resting-state HRV recordings in patients with an anxiety disorder as a primary diagnosis and healthy controls were considered for meta-analysis.', "Meta-analyses were based on 36 articles, including 2086 patients with an anxiety disorder and 2294 controls. Overall, anxiety disorders were characterized by lower HRV [high frequency (HF): Hedges' g\u2009=\u2009-0.29. 95% CI: -0.41 to -0.17, p\u2009<\u20090.001; time domain: Hedges' g\u2009=\u2009-0.45, 95% CI: -0.57 to -0.33, p\u2009<\u20090.001] than controls. Panic disorder (n\u2009=\u2009447), post-traumatic stress disorder (n\u2009=\u2009192), generalized anxiety disorder (n\u2009=\u200968), and social anxiety disorder (n\u2009=\u200990), but not obsessive-compulsive disorder (n\u2009=\u200940), displayed reductions in HF HRV relative to controls (all ps\u2009<\u20090.001).

Example Input: Both BALB/c mice and common voles (Microtus arvalis) are considered highly susceptible to tularemia. However, the common vole is reported to harbour Francisella tularensis in European habitats as well as to survive longer with chronic shedding of the bacterium. The purpose of the present study was to compare the response of these two rodents to a wild Francisella tularensis subsp. holarctica strain infection.', 'Rodents were evaluated for differences in the total antioxidant capacity derived from low-molecular-weight antioxidants, biochemistry including lipid metabolism, tissue bacterial burdens and histopathology following experimental intraperitoneal infection with 160 colony forming units (CFU) pro toto.', 'Bacterial burdens in common voles started to develop later post-exposure and amounted to lower levels than in BALB/c mice. Elevation of liver function enzymes was more pronounced in mice than common voles and there were marked differences in lipid metabolism in the course of tularemia in these two species. Hypertriglyceridemia and hypercholesterolemia developed in mice, while physiologically higher levels of triglycerides and cholesterol showed a decreasing tendency in common voles. On the other hand, the total plasma antioxidant capacity gradually dropped to 81.5% in mice on day 5 post-infection, while it increased to 130% on day 6 post-infection in common voles. Significant correlations between tissue bacterial burdens and several biochemical parameters were found.

Example Input: A cross-sectional study in a general health examination.', 'To investigate the relationship between brachial-ankle pulse wave velocity (baPWV) and lumbar disk herniation (LDH).', 'Lumbar disk herniation (LDH) is a major cause of low back pain and sciatica. Various vascular risk factors such as obesity, diabetes mellitus, and smoking have been reported to be associated with LDH. BaPWV is an early indicator of subclinical atherosclerosis.', 'A total of 490 participants with LDH and 490 participants without LDH were selected for the evaluation of baPWV. BaPWV was measured using an automatic device. The prevalence of LDH was calculated by the quartiles of baPWV levels. Multiple linear regression analysis was performed to evaluate the risk factors for baPWV.', 'LDH patients had significantly higher readings of baPWV compared with non-LDH subjects (P<0.001). The prevalence rate of LDH gradually increased according to baPWV quartiles. In addition, the levels of baPWV tended to increase as the frequency of physical activity reduced. Multiple linear regression analysis showed that body mass index, low-density lipoprotein cholesterol, physical activity, and systolic blood pressure contributed to increased baPWV.
