Figure 2. Incidence of Alzheimer Disease Associated With High vs Low Exposure to Statins.

Figure 2

Hazard ratios depicting the relative risk of Alzheimer disease incidence from 2009 to 2013 for those with high vs low exposure to statins. High-exposure individuals are those with days of filled prescriptions in at least the 50th percentile of days in the mean statin-year in at least 2 years of the period from 2006 to 2008. The low-exposure group used the designated statin, but for fewer days, or later in the sample period. Error bars indicate 95%CI (Table 3). Ator indicates atorvastatin; Pra, pravastatin; Rosu, rosuvastatin; and Sim, simvastatin.
