^aThe fit for the MMSE model was good (χ² [53] = 67.795, P = 0.08, root mean square error of approximation [RMSEA] = 0.050, comparative fit index [CFI] = 0.958).

^bThe fit for the CDR-SoB model was good (χ² [53] = 69.14, P = 0.07, RMSEA = 0.051, CFI = 0.964).

^cFemale sex was used as reference.

^dLow educational level was used as reference.

^eAbsence of CHD was used as reference. CDR-SoB = Clinical Dementia Rating Sum of Boxes. CHD = coronary heart disease. Est = estimate of the effect on intercept and slope of cognition. MMSE = Mini Mental State Examination.
