  Figure 1. Risk of dementia according to atrial fibrillation in the study population (left). Effects of OAC on the risk of dementia in patients with atrial fibrillation (right). Figure courtesy of Kim et al.11) AD = Alzheimer's disease, AF = atrial fibrillation; CI = confidence interval; HR = hazard ratio; OAC = oral anticoagulant, VaD = vascular dementia.

  Figure 2. HRs for dementia per decade of age in the presence of AF. (A) Including stroke during the follow-up. (B) Excluding stroke during the follow-up. The horizontal line (at HR 1) indicates no difference in HRs between the AF and non-AF groups. Figure courtesy of Kim et al.12) AF = atrial fibrillation; HR = hazard ratio.

  Figure 3. Risk of dementia according to oral anticoagulant regimens from Asian, European, and North American populations. Incidences were presented as rates per 100 person-years. Figure courtesy by Kim et al.25) Incidences were presented as rates per 100 person-years. CI = confidence interval; HR = hazard ratio; IPW = inverse probability of treatment weighting; NHIS = National Health Insurance Service; NOAC = non-vitamin K antagonist oral anticoagulant; PSM = propensity score matching. *Incidences and HRs were propensity-weighted; †Incidences were not presented in the article; ‡CHA2DS2-VASc ≤1 (no points for female sex).

Risk of dementia in propensity score-matched patients undergoing ablation or medical therapy (right). Figure courtesy of Kim et al.34) AD = Alzheimer's disease, AF = atrial fibrillation; Tx = treatment; VaD = vascular dementia.

  Figure 5. Association of (A) systolic and (B) diastolic BP at baseline with dementia risk. Figure courtesy of Kim et al.46) BP = blood pressure; CI = confidence interval; HR = hazard ratio. *HRs were calculated with a systolic or diastolic BP of 120 or 80 mmHg as reference.

  Figure 6. Association of hypertension burden during follow-up with dementia risk. Figure courtesy of Kim et al.46) CI = confidence interval; FU = follow-up; HR = hazard ratio; HTN = hypertension. *HRs were calculated with the burden under 40% as reference.
