A restricted cubic spline also indicated a decreased risk of dementia, reaching a low at approximately 1.5 years of cumulative OAC use and stabilizing thereafter. Moreover, OAC use decreased the risk in patients aged 75 years and older (HR 0.84, 95% CI 0.80–0.89), but not in younger patients (HR 0.99, 95% CI 0.90–1.10).Discussion In patients with incident NVAF, OACs were associated with a decreased risk of dementia, particularly in elderly individuals. This warrants consideration when weighing the risks and benefits of anticoagulation in this population.Classification of Evidence This study provides Class II evidence that in patients with NVAF, OAC use (vs nonuse) is associated with a decreased risk of dementia.AF=atrial fibrillation; BMI=body mass index; CPRD=Clinical Practice Research Datalink; DOAC=direct oral anticoagulant; HRs=hazard ratios; IPCW=inverse probability of censoring weighting; NNT=number needed to treat; NVAF=nonvalvular atrial fibrillation; OAC=oral anticoagulant; PS=propensity score; VKA=vitamin K antagonist ER -
