a = between control and MS groups but not differences between both MS groups;

b = between RRMS and BMS groups, after post-hoc analysis;

c = between control and BMS groups, after post-hoc analysis;

d = between control and RRMS groups, after post-hoc analysis;

* = Groups who showed statistical differences for validity of the cue (invalid > valid)
