MSr1, relapse group during relapse; MSr2, relapse group at 1 month after the first assessment; MSr3, relapse group at 3 months after the first assessment; OTS, One touch stockings of Cambridge; OTS-MC 1/2/3/4/5/6, mean choice to correct of 1/2/3/4/5/6 moves of OTS.

Low score denotes better cognition.

^*- Repeated Measures Analysis of Variance (rmANOVA), Greenhouse-Geisser correction for violation of sphericity was used.
