The EQ-5D questionnaire will be used to estimate the impact on subjects quality of life by
different treatments and provides a description of subjects problems by dimensions
(descriptive system), a score for overall self-rated health (visual analogue scale (VAS) as well as an index score (EQ-5D index) .

Подскажите, пожалуйста, description of subjects problems by dimensions - в цифровом выражении? что такое здесь "descriptive system" и "index score"?

[Dimpassy]

by dimensions (descriptive system) - в различных сферах (описательно)
index score - в количественном выражении (в виде индекса EQ-5D)
