Estimated additional years of cognitive aging associated with cytomegalovirus (CMV) seropositivity as compared with being CMV-seronegative, by educational attainment, Health and Retirement Study, 2016. The figure shows modification of the association between CMV serostatus and cognitive function by education; persons with less than a high school diploma had a larger but less precise association with CMV seropositivity than those with higher educational attainment. Estimates were based on the study-sample–specific average change in Telephone Interview for Cognitive Status score per year of age. Data were obtained from the Health and Retirement Study 2016 Core (Early, Version 1.0) Release and the 2016 Venous Blood Study (Early, Version 1.0) Release. Bars, 95% confidence intervals.
