INTRODUCTION The new, five-level version of the EQ-5D (EQ-5D-5L) questionnaire has better psychometric properties than the standard three-level version (EQ-5D-3L), including a reduced ceiling effect. Currently, there are few existing population norms for the EQ-5D-5L. The aims of this study were to provide population norms for the EQ-5D-5L in Poland, based on a representative sample of adults, ...

BACKGROUND The EQ-5D is a brief, generic measure of health status that can be easily incorporated into population health surveys. There are two versions of the EQ-5D for use in adult populations, one with 3 response levels in each of the instrument's 5 dimensions (EQ-5D-3L) and one with 5 levels in each dimension (EQ-5D-5L). We compared the two versions as measures of self-reported health statu...

The synthetic antioxidant ethoxyquin (EQ) is increasingly used in animal feeds and has been candidate for carcinogenicity testing. EQ has the potential for toxicological and adverse health effects for both fish and fish consumers through "carryover" processes. The toxicological aspects of EQ have not been systematically investigated. The present study was performed to investigate the hepatic me...

Objective: To estimate an interim five-level EuroQol five-dimensional (EQ-5D-5L) value set for Poland on the basis of the crosswalk methodology developed by the EuroQol Group. Methods: On the basis of data from 3691 respondents from six European countries, the EuroQol Group has developed a method of obtaining interim value sets for the EQ-5D-5L by means of mapping to the available three-level E...

PURPOSE To describe spherical equivalent (sph eq) refractive errors in preschool members of a Native American tribe with a high prevalence of astigmatism. METHODS Cycloplegic autorefraction measurements were obtained for 819 three- and four-year-old Tohono O'odham children, with follow-up measurements in 146 after 4 to 8 years. RESULTS Mean sph eq was significantly more hyperopic in the ast...

OBJECTIVE To analyse the psychometric properties of the EuroQol questionnaire (EQ-5D) applied to patients with acute coronary syndromes (ACS). SETTING Rehabilitation hospital. PATIENTS AND DESIGN 106 consecutive patients with ACS (51% myocardial infarction, 42% coronary artery bypass grafting, 7% angina) completed the EQ-5D, the 36 item short form health survey (SF-36), and the MacNew quest...

BACKGROUND The Patient Reported Outcomes Measurement Information System 43-item short form (PROMIS-43) and the five-level EQ-5D (EQ-5D-5L) are recently developed measures of health-related quality of life (HRQL) that have potentially broad application in evaluating treatments and capturing burden of respiratory-related diseases. The aims of this study were: (1) to examine their psychometric pro...

BACKGROUND Psoriasis has a significant negative impact on patients' health-related quality of life (HRQOL). This study aims to evaluate HRQOL of adult patients with psoriasis in Iran, and explore the relationship between general and disease-specific outcome measures in psoriasis. METHODS Between May and August 2013, a cross-sectional questionnaire survey of consecutive outpatients was conduct...
