Summary
This study established new population norms for the EQ-5D-3L questionnaire in Poland using a large, representative sample. These findings provide essential reference values for health-related quality-of-life research.
Area of Science:
- Health Economics
- Psychometrics
- Population Health
Background:
- Previous Polish EQ-5D normative data (2010) were based on a small, unrepresentative pilot study from 2008.
- There was a need for updated, robust normative data for the EQ-5D-3L in Poland.
Purpose of the Study:
- To derive population norms for the 3-level EQ-5D (EQ-5D-3L) questionnaire in Poland.
- To utilize a large, representative sample for accurate norm generation.
- To provide reference values for health-related quality-of-life assessments.
Main Methods:
- Stratified random sampling was employed to recruit participants.
- A total of 3941 respondents (aged 18-87) completed the EQ-5D-3L questionnaire and EQ VAS.
- Utility index scores were calculated using the Polish time trade-off value set.
Main Results:
- The study sample accurately represented the Polish population across various demographics.
- Mean EQ-5D-3L scores declined with age, from 0.968 (18-24 years) to 0.730 (≥75 years).
- Pain/discomfort (45.8%) and anxiety/depression (33.3%) were the most reported issues, while self-care limitations were least common (9.4%).
Conclusions:
- The developed Polish population norms for the EQ-5D-3L index, descriptive system, and EQ VAS serve as valuable reference data.
- These normative data are expected to promote the utilization of the EQ-5D-3L in health-related quality-of-life research within Poland.

325
Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area.

01:16Bioequivalence Data: Statistical Interpretation
347
The statistical interpretation of bioequivalence data is a significant aspect of pharmaceutical research. Bioequivalence refers to the absence of any significant difference in the rate and extent to which the active ingredient in pharmaceutical products becomes available at the site of drug action when administered at the same molar dose under similar conditions. This helps determine if different drug products have similar absorption rates, ensuring their interchangeability.Statistical...
