From: Serum glutamine, set-shifting ability and anorexia nervosa

  AN (n = 24) ANRec (n = 18) HC (n = 28)
Trail shifting time 33.3 ± 17.6 29.6 ± 11.3 29.1 ± 8.6
Trail shifting errors 2.0 ± 6.5 0.6 ± 1.0 0.4 ± 0.6
WCST total errors, % 24.0 ± 15.6a** 17.6 ± 8.5 14.9 ± 7.7
WCST perseverative errors, % 13.0 ± 10.4a** 8.7 ± 3.5 7.6 ± 3.4
  1. Values are mean ± SD; *P < 0.05; **P < 0.001.
  2. aComparisons between AN and HC; bcomparisons between AN and ANRec; ccomparisons between ANRec and HC.
  3. AN = anorexia nervosa; ANRec = recovered from anorexia nervosa; HC = healthy controls; WCST = the Wisconsin Card Sorting Test.
