Definition: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: The role of the adipokine, resistin in mediating increases in aortic stiffness is uncertain. We aimed to determine independent relations between circulating resistin concentrations and aortic pulse wave velocity (PWV) and wave reflection in a community-based sample with a high prevalence of untreated hypertension and obesity.', 'Plasma resistin, adiponectin, and C-reactive protein concentrations (ELISA); carotid-femoral (aortic) PWV and the aortic reflected wave index (applanation tonometry and SphygmoCor software) were determined in 683 randomly selected participants of African ancestry from SOWETO, South Africa who had never received antihypertensive therapy.', 'Resistin concentrations were not independently associated with office or 24-h (n=492) blood pressure (BP). In a stepwise regression model with BMI included in the model, age (P<0.0001), mean arterial pressure (P<0.0001), plasma resistin concentrations (P<0.005), female sex (P=0.01), and creatinine concentrations (P<0.01) contributed independently to variations in PWV. Independent relations between resistin concentrations and PWV persisted with further adjustments for C-reactive protein concentrations (P<0.005), and the homeostasis model of insulin resistance (P<0.02). Similar relations were noted with waist circumference rather than BMI in the model. Resistin concentrations were not independently associated with aortic reflected wave index or aortic BP.
Output:
Are circulating resistin concentrations independently associated with aortic pulse wave velocity in a community sample?
