In this paper we investigate reporting heterogeneity in the Visual Analogue Scale (VAS) when it is used to measure current health status in cardiovascular patients. We provide a new framework to identify reporting heterogeneity using quantile regressions. EQ-5D responses are used as a proxy to...

This paper provides an analysis on the use of 15D and EQ-5D to measure health related quality of life. Measures like these are often used interchangeably in cost-effectiveness studies. However, it is unclear whether they measure the same level of health in the same patients. The empirical...
