nearly significantp = 0.052
The ANCOVA revealed no significant subgroup effect (F(1,29) = 2.02, p = 0.17), demonstrating that prosthesis-similarity does not significantly differ because of cause/developmental period of hand loss, and a nearly significant usage effect (F(1,29) = 4.11, p = 0.052), indicating that the relationship between prosthesis categorisation and usage is relatively independent from potential subgroup effects.
