of borderline significanceP = 0.054
Specifically, the Group × Domain interaction was again significant (β = 2.36 ± 1.00, Z = 2.37, P = 0.018) and showed that the HD group were clearly less cognitively motivated than controls (χ 2 = 12.6, P = 0.0008), with group differences in the physical domain of borderline significance (χ 2 = 3.70, P = 0.054; Supplementary Table 2 ).
