All three study groups judged the same 17 hypothetical EQ-5D health states, each state comprising the same five health domains. The patients did not know that apart from these 17 states their own health status was also included in the set of states they were assessing. Three different measurement strategies were applied: 1) ranking of the health states; 2) placing all the health states simultaneously on a visual analogue scale (VAS); 3) separately assessing the health states with the time trade-off (TTO) technique. Regression analyses were performed
to determine whether differences in the VAS and TTO can be ascribed to specific health domains. In addition, effect of being member of one of the two patient groups and the effect of the assessment CHIR98014 concentration of the patients’ own health status was analyzed.
Results: Except for some moderate divergence, no differences were found between patients and healthy people for the ranking task or for the VAS. For the time trade-off technique, however, large differences were observed between patients and Dibutyryl-cAMP mouse healthy people. The regression analyses for the effect of belonging to one of the patient groups and the effect of the value assigned to the patients’ own health state showed that only
for the TTO these patient-specific parameters did offer some additional information in explaining the 17 hypothetical EQ-5D states.
Conclusions: Patients’ assessment of health states is similar to that of the general population when the judgments are made under conditions that are defended by modern measurement theory.”
“The incorporation of biopolymers, such as chrome shavings and buffing dust, into rubber blends makes it possible to obtain biodecomposable collagen-elastomer materials with good utility GSK1120212 price properties. It is the presence of a biopolymer in multicomponent polymeric materials that facilitates enzymatic hydrolysis and results in biodecomposition through the loss of cohesiveness and polymer scattering. The undertaking of such original studies
was justified by the benefits resulting from a new generation of polymeric materials and the need for a solution to the problem of growing amounts of wastes by waste management in the tanning industry. In this study, the effect of a mixture of chrome shavings and buffing dust on the properties of nitrile rubbers was examined. The dust and shavings, in a 1: 1 proportion, were mixed with 5 parts by weight of zinc oxide and, in this form, was added to the rubber blends. (C) 2011 Wiley Periodicals, Inc.
