Table 4 Coefficients (standard error) of different regression analyses on TTO values for the general population and for the two patient groups (for each domain 2 dummies expressing the step from level 1 to level 2 (2), and the step from level 2 to level 3 (3))
From: Are patients' judgments of health status really different from the general population?
