Table 3 Linear regression: the influence of language version on EQ-5D utility and visual analog scale scores

From: Do English and Chinese EQ-5D versions demonstrate measurement equivalence? an exploratory study

Dependent variable Unadjusted effect size (95%CI) p-value Adjusted effect size (95%CI)* p-value
EQ-5D utility score 0.01 (-0.07, 0.09) 0.851 -0.05 (-0.14, 0.03) 0.214
EQ-VAS score 2.7 (-3.5, 8.8) 0.396 -4.1 (-11.6, 3.3) 0.276
  1. 95%CI = 95% confidence interval; Chinese language was the reference group; EQ-VAS = EQ-5D Visual Analog Scale *Adjusted for the influence of age, gender, years of education, employment status and pain VAS score.
