Given the task definition and input, reply with output. 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.

We studied the association between polymorphisms in the UCP genes and diabetes complications in patients with type 1 diabetes.', 'We analyzed 227 patients with type 1 diabetes using PCR and subsequent cleavage by restriction endonucleases for the promoter variants A-3826G in the UCP1 gene, G-866A in the UCP2 gene, and C-55T in the UCP3 gene.', 'No effect of the A-3826G polymorphism in the UCP1 gene on diabetes complications was found. Patients who were heterozygous or homozygous for the G-866A polymorphism in the UCP2 gene or the C-55T polymorphism in the UCP3 gene had a significantly reduced prevalence of diabetic neuropathy (UCP2: odds ratio 0.44 [95% CI 0.24-0.79], P = 0.007; UCP3: 0.48 [0.25-0.92], P = 0.031), whereas there was no association with other diabetes complications. This effect was stronger when G-866A and C-55T occurred in a cosegregatory manner (UCP2 and UCP3: 0.28 [0.12-0.65], P = 0.002). Furthermore, a multiple logistic regression model showed an age- and diabetes duration-independent effect of the cosegregated polymorphisms on the prevalence of diabetic neuropathy (P = 0.013).
