3. Figure 2
Forest plot showing the individual and pooled adjusted hazard ratios (HR) of incident dementia comparing patients with atrial fibrillation (AF) vs those without AF. Square boxes denote HR. The dimension of each square box denotes the weight from random effect analysis. Horizontal lines represent 95% confidence interval (CI). The study by Rastas et al14 did not report the adjusted HR and was included for sensitivity analysis (see Methods).

Effect of single study withdrawal on the pooled hazard ratio (HR) of incident dementia comparing patients with atrial fibrillation (AF) vs those without AF. Presence of AF consistently increased the risk of incident dementia also after excluding each study in turn.
