Intercept | 0.2735 | [0.09, 0.46] | 2.85 | .004 |
Yrs.PS (yrs) | 0.0110 | [−0.45, 0.47] | 0.04 | .963 |
Yrs.PS2 | 0.0078 | [−0.09, 0.11] | 0.15 | .879 |
ΔTime (10 hrs) | 0.0344 | [0.00, 0.07] | 2.04 | .041 |
Note. Parameter estimates for Yrs.PS in years and the estimates for ΔTime in 10-hour units. We tested the interaction of Yrs.PS and ΔTime, which was marginally significant (p = 0.06; b = 0.027), suggesting the effect of increased time in therapy was larger for later post-stroke times. This interaction was marginal and did not improve the fit of the model, so the main effects model is presented.
