Table 4.

Mean EQ-5D scores and QALYs over 12 months for primary analysis

Health outcome Leaflet and advice (n = 65), mean (s.d.) Joint protection only (n = 62), mean (s.d.) Hand exercises only (n = 65), mean (s.d.) Joint protection plus hand exercises (n = 65), mean (s.d.)
EQ-5D (imputed)
    Baseline 0.623 (0.26) 0.646 (0.25) 0.645 (0.21) 0.659 (0.26)
    3 months 0.665 (0.24) 0.682 (0.17) 0.660 (0.22) 0.676 (0.24)
    6 months 0.658 (0.25) 0.635 (0.25) 0.692 (0.18) 0.672 (0.24)
    12 months 0.634 (0.22) 0.684 (0.19) 0.708 (0.18) 0.659 (0.27)
QALYs (imputed)
    QALYs at 12 months 0.649 (0.21) 0.660 (0.19) 0.682 (0.16) 0.668 (0.23)
    QALYs at 12 months, predicted meana 0.662 (0.17) 0.659 (0.16) 0.681 (0.14) 0.658 (0.16)

aValues are predicted mean scores obtained from the multiple regression equation when controlling for baseline imbalances. None of the differences in EQ-5D or QALYs between the trial arms were statistically significant (Kruskal–Wallis test).
