+Percentages in the first coloun under the socio-demographic and the 5 dimensions of the EQ-5D-3L descriptive system show the proportion of the health concentration index explained by each model. Percentages under each variable then show relative contribution to the explained portion of the health concentration index.
The income-related health concentration index based on overall self-assessed health measured on the EQ VAS was the highest in the US with a value of 0.0234. Socio-demographic indicators explained 21.7% of the concentration index in the US. In total 74.9% of the health concentration index was explained by reported problems along the 5 dimensions of the EQ-5D-3L descriptive system in the US.
