Diabetic Peripheral Microvascular Complications: Relationship to Cognitive Function

Table 2

CANTAB test data for the three study groups across the various test domains. Pattern recognition memory (PRM), reaction time (RT), and rapid visual information processing (RVP) differed among the study groups with only RT and RVP remaining significantly different after adjusting for age.
