...In contrast to EQ-5D-3L, currently, no specific set of social health status preference valuations for the German version of the instrument exists to convert each health state described by EQ-5D-5L to a preference-based summary score on a 1 (full health) to 0 (dead) scale, which allows quality-adjusted life year (QALY) calculations....
