One of the six trials which incorporated the EQ-5D used the 3-Level version while the other five used the 5-Level version. Responses to the 3-Level version were dichotomized for the purposes of this Known Groups Analysis as ‘No problem’ vs. ‘Some problem’/‘Unable to…’, while responses to the 5-Level version were dichotomized as ‘No problem’ vs. ‘Slight’/‘Moderate’/‘Severe’/‘Unable to…’
All differences were statistically significant, p < 0.05, EQ-5D: EuroQol-5 Dimension
