Figure 4. Population Attributable Fraction.

Bars represent the percent of dementia that would be theoretically reduced if the individual lesion were reduced to 0, weighted to account for interdependence between variables. Error bars represent 95% CIs. ACT = Adult Changes in Thought; HS = hippocampal sclerosis; LATE-NC = limbic-predominant age-related TDP-43 encephalopathy; LBD = Lewy body disease; μVBI = microvascular brain injury; NFT = neurofibrillary tangle; NP = neuritic plaque; OR = odds ratio.
