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

Best fitting model parameters (based on Wald Test)	Estimate	SE	t-Value	p-Value
Intercept	15.56	1.83	8.50	< 0.001
Lesion Contrast1	− 0.07	1.29	− 0.06	0.96
Lesion Contrast2	0.50	0.46	1.08	0.28

Note. The best fitting model included only the contrast coded predictors of lesion location (AIC = 1245.5; BIC = 1261.6) with 187 individuals across 19 different studies. Adding the factors of Sex, Age, and Days Since Stroke (DSS) did not significantly improve the fit of the model (AIC = 1247.7, BIC = 1273.5, Wald Test p = 0.28). Sex was coded as female = 0·5, male = − 0·5; age was centred around overall mean age = 58·56; and days since stroke (DSS) was square root transformed (rtDSS) and then centred around the root-transformed mean. This led to an approximately normal distribution of residuals and homoscedasticity of the residuals. Orthogonal contrasts for lesion location as cortical, mixed, and sub-cortical stroke as 1, 0, − 1, respectively for Contrast 1 (Contrast 2 = − 1, 2, − 1). AIC Akaike information criterion.
