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.

[EX Q]: To assess the impact of an audiovisual (AV) biofeedback on intra- and interfraction tumor motion for lung cancer patients.', 'Lung tumor motion was investigated in 9 lung cancer patients who underwent a breathing training session with AV biofeedback before 2 3T magnetic resonance imaging (MRI) sessions. The breathing training session was performed to allow patients to become familiar with AV biofeedback, which uses a guiding wave customized for each patient according to a reference breathing pattern. In the first MRI session (pretreatment), 2-dimensional cine-MR images with (1) free breathing (FB) and (2) AV biofeedback were obtained, and the second MRI session was repeated within 3-6 weeks (mid-treatment). Lung tumors were directly measured from cine-MR images using an auto-segmentation technique; the centroid and outlier motions of the lung tumors were measured from the segmented tumors. Free breathing and AV biofeedback were compared using several metrics: intra- and interfraction tumor motion consistency in displacement and period, and the outlier motion ratio.', 'Compared with FB, AV biofeedback improved intrafraction tumor motion consistency by 34% in displacement (P=.019) and by 73% in period (P<.001). Compared with FB, AV biofeedback improved interfraction tumor motion consistency by 42% in displacement (P<.046) and by 74% in period (P=.005). Compared with FB, AV biofeedback reduced the outlier motion ratio by 21% (P<.001).

[EX Q]: There is a strong association between migraine and depression. The aim of this study is to identify migraine-specific factors involved in this association.', 'We conducted a cross-sectional study in a large, well-defined cohort of migraine patients (n=2533). We assessed lifetime depression using validated questionnaires, and diagnosed migraine based on the International Classification of Headache Disorders III-beta criteria. Multivariate regression analyses were conducted.', 'Of the 2533 migraineurs that were eligible, 1137 (45%) suffered from lifetime depression. The following independent factors were associated with an increased depression prevalence: i) migraine-specific risk factors: high migraine attack frequency and the presence of allodynia, ii) general factors: being a bad sleeper, female gender, high BMI, being single, smoking, and a low alcohol consumption.

[EX Q]: Physicians refer proteinuric patients to kidney biopsy in order to clarify the issue of underlying renal disease. We compared kidney biopsy results with classical outcome parameters in a large cohort of patients with biopsy proven glomerulonephritis (GN).', 'In a retrospective analysis, 2687 patients with different forms of GN from 123 Austrian centres were investigated. Patient characteristics, the diagnosis of GN and its respective subtype and clinical symptoms such as arterial hypertension, haematuria, amount of proteinuria and estimated glomerular filtration rate (eGFR) were tested for their association with all-cause mortality and progression to end-stage renal disease (ESRD).', "During a median follow-up of 1299months (IQR 896; 1777), 688 patients (256%) died and 718 patients required dialysis (294%). In multivariate Cox's regression analysis age (HR 106), female sex (HR 071), eGFR (HR 074), the diagnosis of GN and its subtypes predicted patient survival (all P<001), whereas the amount of proteinuria was not associated with patient survival. The incidence of progression to ESRD was associated with female sex (HR 071), eGFR (HR 065), amount of proteinuria (HR 115) and the diagnosis of GN and its subtypes (all P<001). Nephrotic or nephritic syndromes were not associated with patient survival or progression to ESRD and did not add further predictive value to outcome of GN.
