FLMs and permutation F-tests comparing 24-hour activity profiles between typically-developing and syndrome groups
Upper panel presents the mean 24-hour activity profile of each group, converted to functional form via Fourier expansion model. Lower panel presents the non-parametric permutation F-test results. The lines correspond to the times at which activity levels significantly differed between the syndrome and TD groups (p = .01), and describe the direction of the effect
