Model comparisons for the effects of lesion hemisphere on motor outcome, Fugl-Meyer Arm score.

Best fitting model parameters (based on Wald Test)	Estimate	SE	t-Value	p-Value
Intercept	16.54	1.68	9.86	< 0.001
Lesion hemisphere	0.35	0.99	0.36	0.72

Note. The best fitting model included only the contrast coded predictor of lesion hemisphere (AIC = 1192.8; BIC = 1205.5) with 179 individuals across 20 different studies. Adding the factors of Sex, Age, and Days Since Stroke (DSS) did not significantly improve the fit of the model (AIC = 1196.5, BIC = 1218.8, Wald Test p = 0.53). Hemisphere was coded right = 0·5, left = − 0·5; sex was coded as female = 0·5, male = − 0·5; age was centred around overall mean age = 58·56; and DSS was square root transformed and then centred around the root-transformed mean. This led to an approximately normal distribution of residuals and homoscedasticity of the residuals. AIC Akaike information criterion. BIC Bayesian information criterion.
