2×2 Contingency table summarizing association between findings of transcranial magnetic stimulation (TMS) and diffusion tensor imaging (DTI)

		Contralateral corticospinal tracts (CST) detected by: DTI

^aDTI yes: presence of contralateral CST reconstructed by DTI tractography. ^bDTI no: absence of contralateral CST reconstructed by DTI tractography. ^cTMS yes: presence of TMS‐induced motor evoked potential (MEP) responses from electromyography (EMG) recordings on the more‐affected upper extremity (UE). ^dTMS no: absence of TMS‐induced MEP responses from EMG recordings on the more‐affected UE.
