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: Biomarkers predictive of recovery from acute kidney injury (AKI) after liver transplantation (LT) could enhance decision algorithms regarding the need for liver-kidney transplantation or renal sparing regimens. Multianalyte plasma/urine kidney injury protein panels were performed immediately before and 1 month post-LT in an initial test group divided by reversible pre-LT AKI (rAKI = post-LT renal recovery) versus no AKI (nAKI). This was followed by a larger validation set that included an additional group: irreversible pre-LT AKI (iAKI = no post-LT renal recovery). In the test group (n = 16), six pre-LT plasma (not urine) kidney injury proteins (osteopontin [OPN], neutrophil gelatinase-associated lipocalin, cystatin C, trefoil factor 3, tissue inhibitor of metalloproteinase [TIMP]-1, and β-2-microglobulin) were higher in rAKI versus nAKI (P < 0.05) and returned to normal values with renal recovery post-LT. In the validation set (n = 46), a number of proteins were significantly higher in both rAKI and iAKI versus nAKI. However, only pre-LT plasma OPN (P = 0.009) and TIMP-1 (P = 0.019) levels were significantly higher in rAKI versus iAKI. Logistic regression modeling was used to correlate the probability of post-LT rAKI, factoring in both pre-LT protein markers and clinical variables. A combined model including elevated OPN and TIMP-1 levels, age <57, and absence of diabetes had the highest area under the curve of 0.82, compared to protein-only and clinical variable-only models.

Example Input: A limited amount of literature suggests that plasma leptin concentrations are reduced with habitual physical activity in men and non-pregnant women. We investigated the relationship between maternal physical activity and plasma leptin during early pregnancy.', 'The study population included 879 normotensive, non-diabetic pregnant women who reported physical activity type, frequency, and duration in early pregnancy. Plasma leptin, measured in blood samples collected <16 weeks gestation, were determined using enzyme immunoassays. Weekly duration (h/week) and energy expended on recreational physical activity [metabolic equivalent score (MET)-h/week] were categorized by tertiles among active women. Physical activity intensity was categorized as none, moderate (<6 MET) and vigorous (> or =6 MET). Differences in leptin concentrations across categories were estimated using linear regression procedures.', 'Mean leptin was 5.8 ng/ml lower among active versus inactive women (P=0.001). Mean leptin was lower among women in the highest levels (>12.8 h/week) of time performing physical activity (-8.1 ng/ml, P<0.001) and energy expenditure (>70.4 MET-h/week) (-8.3 ng/ml, P=0.001) compared with inactive women. Leptin was inversely associated with the intensity of physical activity.

Example Input: : Trauma center physicians need to know the patient's prognosis to make appropriate clinical decisions when they take over the care of a transferred patient. We sought to compare the survival of injured patients after transfer to a trauma center with survival from a comparable time after injury among patients who had been admitted to the trauma center directly from the scene of injury.", ': Study included 2,867 patients 18 years to 84 years of age with at least one Abbreviated Injury Scale score >/=3 injury transferred to a trauma center and 7,570 patients admitted directly to a trauma center. The outcome was death within one year after injury. Cox proportional hazards model for death was used accounting for time since injury, adjusted for age group, gender, injury severity, injury mechanism, and comorbidities.', ': Overall, there was almost no increase in the adjusted risk of death for transfer patients in the year after injury [hazard ratio (HR) 0.99, 95% confidence interval (CI) 0.78, 1.27]. The adjusted risk of death was higher in transfer patients than nontransfer patients between 50 days and 365 days after injury (HR 1.28, 95% CI 0.79, 2.07), but not within the first 50 days (HR 0.95, 95% CI 0.76, 1.18). However these modest differences in survival within each period were not statistically significant.
