Model 3 (bold), which included both effort and success predictors, was the selected model for each group based on AIC and log-likelihood ratio tests. However, note that whereas the coefficient of the effort term is largely significant in all 3 models, the coefficient for success is only significant in the LH model (P < 0.001). AIC, Akaike information criterion; LH, left hemiparesis; LLH, log-likelihood; Observ., observation; RH, right hemiparesis.
*P < 0.05, **P < 0.01, ***P < 0.001.
