Model comparisons for the effects of corticospinal tract asymmetry index on motor outcome, Fugl-Meyer Arm score.

Parameters of the best fitting model (by Wald Test)	Estimate	SE	t-Value	p-Value
Intercept	13.20	1.65	8.01	< 0.001
Corticospinal tract asymmetry index	0.44	8.64	0.05	0.96
MEP	5.70	2.77	2.06	0.05

Note. The best fitting model included MEP presence and the Corticospinal tract asymmetry index (AIC = 137.7, BIC = 142.6, Wald Test p = 0.05) and was based on 20 individuals from 2 different studies. The fit of this model was significantly better than Corticospinal tract asymmetry alone (AIC = 139.51; BIC 143.49). Corticospinal tract asymmetry index was centred around the group mean of 0·19. Motor Evoked Potential (MEP) was coded 0·5 = MEP positive, − 0·5 = MEP negative. There was an approximately normal distribution of residuals and homoscedasticity of the residuals. AIC Akaike information criterion. BIC Bayesian information criterion. Italics indicates significant effect (p ≤ 0.05).
