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: This study was conducted to measure the corneal thickness changes associated with wearing 30-day tisilfocon A (Dk = 163) and 6-day etafilcon A (Dk = 28) contact lenses. The probable cause of the outcomes is discussed.', 'Thirty subjects were fitted with Menicon Z rigid gas-permeable (RGP) contact lenses and a control group (n = 30) was fitted with ACUVUE hydrogel lenses, at two study sites. After a 2-week period of daily wear, subjects began prolonged wear. Measurements were performed at the dispensing visit, and then at the 2-week daily wear, the 1-week, 6-month, and 12-month extended- and continuous-wear visits.', 'Repeated measures analysis of covariance was performed on mean corneal thickness. There was a significant increase in corneal thickness in the hydrogel lens extended-wear group compared to the RGP group (P = 0.03). The mean corneal thickness in the ACUVUE group was 2.58% higher at the 2-week daily wear visit, 2.38% higher at the 1-week extended-wear visit, 2.96% higher at the 6-month, and 2.97% higher at the 1-year visit compared to the RGP continuous-wear patients.

Example Input: To compare two solutions for fluid resuscitation in post-coronary artery bypass grafting (CABG) surgery patients: Ringer's lactate (RL) versus a new solution containing half-molar sodium-lactate (HL).", 'Prospective randomized open label study.', 'The first 12 h post-CABG surgery in an intensive care unit (ICU).', 'There were 230 patients enrolled in the study: 208 were analyzed, with 109 from the HL group and 99 from the RL group.', 'Patients received over the first 12 h post-CABG 10 ml kg BW(-1) HL solution in the HL group versus 30 ml kg BW(-1) of RL solution in the RL group.', 'Hemodynamic status, body fluid balance and inotrope utilization were compared in the two groups. Post-operative cardiac index increase was significantly higher in HL than in RL (P = 0.02), while mean arterial pressure and other hemodynamic parameters were comparable together with urinary output, indicating similar tissue perfusion in both the groups despite a much lower fluid infusion in the HL group. Therefore, a significant negative fluid balance was achieved in the HL but not in the RL group (-790 +/- 71 vs. +43 +/- 115 mL 12 h(-1), P < 0.0001 for HL and RL, respectively). None of the enrolled patients exhibited side effects related to the treatment.

Example Input: The aim of this research was to assess the effect of mouth rinses with and without alcohol on the hardness of dental nano-filled composite.', "The micro-hardness of fifty circular disk shaped specimens of 7 mm x 2 mm were measured after 14 days. Specimens were immersed into alcohol containing (Listerine and Colgate Perioguard) and alcohol-free (Prodent and Sensodyne Oral antiseptic) mouth rinse solutions. Artificial saliva served as the control. Vickers Micro-hardness was measured with a 30gram load for 30 seconds dwell time by using a diamond indenter. Significant differences were represented by p<0.05, whereas highly significant difference represented by p<0.01. The level of significance (p) was calculated with the help of repeated measure ANOVA. For multiple comparisons, Tukey's multiple comparison test was used.", 'Statistical analysis revealed highly significant difference between specimens immersed in artificial saliva (control) and Listerine (p<0.01). Whereas significant difference were observed between control and Colgate Periogard (p<0.05). However, no significant difference was observed on comparing Prodent and Sensodyne Oral antiseptic mouth rinses with control group(p>0.05). Control specimens depicted highest value of micro-hardness(60.5746 ± 3.2703) compared to the lowest value seen in specimens immersed in Listerine solvent(54.4687 ± 1.0937).
