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: Despite evidence supporting the importance of breastfeeding to child health, breastfeeding practices remain suboptimal in Vietnam. There is currently little evidence on the importance of breastfeeding in the prevention of morbidity during infancy in Vietnam. In order to provide country specific data for policy makers to support breastfeeding friendly policies and programs, analysis was undertaken on a cross-sectional dataset to investigate the association between breastfeeding practices and prevalence of diarrhea and acute respiratory infection (ARI) among infants aged 0-5 months.', 'Data on socio-demographic characteristics, infant feeding practices and prevalence of diarrhea and ARI were obtained from 6,068 mother-child dyads in 11 provinces of Vietnam in 2011. Multivariate logistic regression was used to examine the associations between breastfeeding practices and child illnesses.', 'On average, the prevalence of diarrhea and ARI among infants 0-5 months was 5.3% and 24.5%, respectively. Though half of all infants were breastfed within one hour of birth, 73.3% were given prelacteal foods in the first three days after birth. Only 20.2% of children 0-5 months old were exclusively breastfed, while 32.4% were predominantly breastfed and 47.4% partially breastfed. After adjusting for confounders, early initiation of breastfeeding was associated with lower prevalence of diarrhea [adjusted odds ratio (AOR)=0.74 (95% CI 0.58, 0.93)], while prelacteal feeding was associated with higher prevalence [AOR=1.53 (95% CI 1.15, 2.03)]. Compared to infants who were exclusively breastfed, infants who were predominantly [AOR=1.52 (95% CI 1.05, 2.21)] or partially breastfed [AOR=1.55 (95% CI 1.07, 2.24)] were more likely to have diarrhea. Prelacteal feeding [AOR=1.16 (95% CI 1.01, 1.33)] and partial breastfeeding [AOR relative to exclusive breastfeeding=1.24 (95% CI 1.03, 1.48)] were associated with higher prevalence of ARI. While the protective effects of exclusive breastfeeding against diarrhea declined with child age, this effect for ARI appears to have remained constant.

Example Input: To investigate the relationship between tissue elasticity before and after antiviral therapy and shear wave as well as strain elastography.', 'FibroScan and real-time tissue elastography were performed before and after antiviral therapy for chronic hepatitis C, and treatment efficacy and elastographic findings were comparatively analyzed. Elasticity was evaluated by measuring liver stiffness (LS) in kilopascals using FibroScan, and the liver fibrosis index (LFI) was assessed by real-time tissue elastography.', 'LS and LFI correlated well before and after therapy (r = 0.567, p = 0.003 and r = 0.576, p = 0.002, respectively). In the group without a sustained virological response (SVR), LS increased in 4 of 5 patients. Patients with an increase in both LS and LFI were all in the non-SVR group (3/3, 100%). In addition, LS increased in all patients except 1 in the non-SVR group (4/5, 80%). In the SVR group, both LS and LFI decreased in all patients except 1 (18/19, 94.7%). In the patient with an increase in LS despite achieving SVR, LS decreased quickly after alcohol cessation.

Example Input: Three surgical approaches: cochleostomy (C), round window (RW), and extended round window (ERW); and two electrodes types: lateral wall (LW) and perimodiolar (PM), account for the vast majority of cochlear implantations. The goal of this study was to analyze the relationship between surgical approach and electrode type with final intracochlear position of the electrode array and subsequent hearing outcomes.', 'Comparative longitudinal study.', 'One hundred postlingually implanted adult patients were enrolled in the study. From the postoperative scan, intracochlear electrode location was determined and using rigid registration, transformed back to the preoperative computed tomography which had intracochlear anatomy (scala tympani and scala vestibuli) specified using a statistical shape model based on 10 microCT scans of human cadaveric cochleae. Likelihood ratio chi-square statistics were used to evaluate for differences in electrode placement with respect to surgical approach (C, RW, ERW) and type of electrode (LW, PM).', 'Electrode placement completely within the scala tympani (ST) was more common for LW than were PM designs (89% vs. 58%; P<0.001). RW and ERW approaches were associated with lower rates of electrode placement outside the ST than was the cochleostomy approach (9%, 16%, and 63%, respectively; P<0.001). This pattern held true regardless of whether the implant was LW or PM. When examining electrode placement and hearing outcome, those with electrode residing completely within the ST had better consonant-nucleus-consonant word scores than did patients with any number of electrodes located outside the ST (P=0.045).
