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.

Input: Consider Input: NI margins have to be chosen appropriately to control the risk of degradation of treatment effects in non-inferiority (NI) trials. We aimed to study whether the current choice of NI margins protects sufficiently against a degradation of treatment effect on an average.', 'NI trials reflecting current practice were assembled and for each trial, the NI margin was translated into a likelihood of degradation. The likelihood of degradation was calculated as the conditional probability of a treatment being harmful given that it is declared non-inferior in the trial, using simulation. Its distribution among the NI trials was then studied to assess the potential risk of degradation.', "The median (lower/upper quartile) NI margin among 112 binary outcome NI trials corresponded to an odds ratio of 0.57(0.45, 0.66), while among 38 NI trials with continuous outcome, to a Cohen's d of -0.42(-0.54, -0.31) and a hazard ratio of 0.82(0.73, 0.86) among 24 survival outcome NI trials. Overall, the median likelihood of degradation was 56% (45%, 62%).

Input: Consider Input: The B cell is a key player in the pathogenesis of systemic lupus erythematosus (SLE). Loss of B cell tolerance resulting in autoantibody production and immune complex formation and deposition are central features of the disease. B cell overactivity is a hallmark of SLE and molecular abnormalities in B cell signaling cascade have been described.', 'In this review, we will focus on the aberrant phenotype of B cell signaling in patients with lupus. We will also discuss data stemming from the use of small molecules that have recently been recognized to target important steps of the B cell signal transduction pathways with therapeutic implications for SLE.

Input: Consider Input: To investigate the differential expressions of nucleolin in invasive cervical squamous cell carcinoma, cervical intraepithelial neoplasms (CIN) and normal cervical epithelial tissues and explore the role of nucleolin in the carcinogenesis and progression of cervical squamous cell carcinoma.', 'Fifty specimens of invasive cervical squamous cell carcinoma, 65 specimens of CIN, and 60 adjacent normal cervical epithelial tissue specimens were examined immunohistochemically for nucleolin expression. The correlation of nucleolin expression levels with histological grades of invasive cervical squamous cell carcinoma and CIN were analyzed.', 'The specimens of invasive cervical squamous cell carcinoma showed a significantly higher positivity rate for nucleolin expression than CIN and normal cervical epithelial tissues, and the rate in CIN tissues was significantly higher than that in normal cervical epithelial tissues (P<0.01). The expression level of nucleolin was significantly higher in invasive cervical squamous cell carcinoma than in CIN and normal cervical epithelia tissues, and higher in CIN than in normal cervical epithelia tissues, whose immunostaining scores were 7.6±0.3, 6.1±0.2, and 3.0±0.2, respectively (P<0.01). The mean nucleolin immunostaining score was significantly higher in poorly and moderately differentiated than in highly differentiated cervical squamous cell carcinoma (7.9 vs 7.1, P<0.01), and higher in high grade CIN than in low grade CIN tissues (6.0 vs 4.0, P<0.01).
