Given the task definition, example input & output, solve the new input case.
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: Chronic rhinosinusitis (CRS) is a heterogeneous disease with an uncertain pathogenesis. Group 2 innate lymphoid cells (ILC2s) represent a recently discovered cell population which has been implicated in driving Th2 inflammation in CRS; however, their relationship with clinical disease characteristics has yet to be investigated. The aim of this study was to identify ILC2s in sinus mucosa in patients with CRS and controls and compare ILC2s across characteristics of disease. A cross-sectional study of patients with CRS undergoing endoscopic sinus surgery was conducted. Sinus mucosal biopsies were obtained during surgery and control tissue from patients undergoing pituitary tumour resection through transphenoidal approach. ILC2s were identified as CD45(+) Lin(-) CD127(+) CD4(-) CD8(-) CRTH2(CD294)(+) CD161(+) cells in single cell suspensions through flow cytometry. ILC2 frequencies, measured as a percentage of CD45(+) cells, were compared across CRS phenotype, endotype, inflammatory CRS subtype and other disease characteristics including blood eosinophils, serum IgE, asthma status and nasal symptom score. 35 patients (40% female, age 48 17 years) including 13 with eosinophilic CRS (eCRS), 13 with non-eCRS and 9 controls were recruited. ILC2 frequencies were associated with the presence of nasal polyps (P = 0.002) as well as high tissue eosinophilia (P = 0.004) and eosinophil-dominant CRS (P = 0.001) (Mann-Whitney U). They were also associated with increased blood eosinophilia (P = 0.005). There were no significant associations found between ILC2s and serum total IgE and allergic disease. In the CRS with nasal polyps (CRSwNP) population, ILC2s were increased in patients with co-existing asthma (P = 0.03). ILC2s were also correlated with worsening nasal symptom score in CRS (P = 0.04).
Output: 1
There is a line in the passage which say 'The aim of this study was...' which suggests that it is talking about a specific aim. Hence, the output should be 1 as this passage has a definite aim.

New input case for you: Fracture risk in type 1 diabetes (T1D) is supposed to be underestimated by bone mineral density (BMD). Individuals with T1D had more prevalent fractures in a cross-sectional study. Serum levels of pentosidine, an advanced glycation end product, and poor glycaemic control were associated with prevalent fractures independent of BMD.', 'Type 1 diabetes (T1D) is associated with increased fracture risk. Bone mineral density (BMD) underestimates the risk of fractures in some individuals. The accumulation of advanced glycation end products (AGEs) impairs bone matrix and reduces bone strength.', 'In a cross-sectional study, 128 men and premenopausal women with T1D were evaluated. We compared traditional risk factors for fractures, BMD, parameters of bone metabolism and AGEs in individuals with and without prevalent fractures. An independent association of serum AGE levels with prevalent fractures was investigated.', 'Individuals with prevalent fractures exhibited a longer duration of T1D, higher HbA1c and more diabetic-related complications. BMD at the femoral neck (z-score -0.760.94 vs. -0.231.02; p=0.031) and total hip (z-score -0.540.93 vs. 0.111.11; p=0.017) was lower in those with prevalent fractures. Individuals with fractures had higher pentosidine levels (164.153.6 vs. 133.240.4; p=0.002). The levels of N--(carboxymethyl)-lysine (CML) and endogenous secretory receptor for AGEs (esRAGE) did not significantly differ. Multivariate logistic regression analysis adjusted for age, BMI, family history of fractures, smoking, vitamin D deficiency, BMD at lumbar spine, femoral neck and total hip identified pentosidine levels and HbA1c as independent factors associated with prevalent fractures (odds ratio 1.02, 95% CI 1.00-1.03/pmol/ml increase of pentosidine; p=0.008 and odds ratio 1.93, 95% CI 1.16-3.20 per percentage increase of HbA1c; p=0.011).
