^*The role of attention in EF has been widely debated in the literature. We include Continuous Performance Test as

a measure of EF because this is how it was classed by authors.

^#Summed frequency counts of 328 individual measures of EF each with a frequency usage < 2.5%. Only 12 of these were rating scales with Dysexecutive (DEX) questionnaire, Diabetes Related Executive Functioning Scale (DREFS), Decision-Making Quality Scale (count = 2 each) as the most outstanding. The rest of the measures were performance-based, Controlled Oral Word Association Test (COWAT, count = 51) the most outstanding.
