Characteristics of the whole sample divided in according to no aMCI or dMCI, with aMCI, and with dMCI (Standard Deviations in brackets unless otherwise stated as % for categorical variables). Dementia cases have been excluded.

Note. All percentages are column percentages. eGFR = estimated glomerular filtration rate. SD = standard deviation. CVD morbidity = cerebrovascular disease morbidity; this includes history of myocardial infarction, history of stroke, diagnosis of diabetes, and hypertension. BMI = Body Mass Index. GDS = Geriatric Depression Scale. APOEe4 = Apolipoprotein E allele e4. The Pearson’s chi square was used for categorical variables.
