R2 values obtained by regression analysis for the prediction of motor recovery of the arm at 2, 6 ,and 12 months post-stroke from five single predictor variables measured at baseline, and for the prediction of motor recovery of the arm at 6 and 12 months post-stroke from five single predictor variables measured at 2 months after the onset of stroke
