Each score of cognitive test(A Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet, stroop test), Positive and Negative Syndrome Scale, Hamilton rating scale for Depression were assessed. Statistical analysis of the relationship between various tests of A Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet and metabolic syndrome were performed using ANCOVA and logistic regression.
Schizophrenia patients with lower score on construction praxia were likely to be included in Metabolic syndrome group. However, there were no significant relationships in other tests between the two groups.
