B, Longitudinal effects. SSS scores at baseline and follow-up examinations are compared between the NAA/CrIncrease and NAA/CrNo Increase groups, correcting for the ipsilesional change in NAA/Cr. Values are means ± SEM. Black circles, contralesional NAA/CrIncrease group; white circles, contralesional NAA/CrNo Increase group.
