Log OR of dementia as a function of trends and variances of total recall score with power transformation a, adjusted for education, race/ethnicity, and gender. SD=standard deviation (estimated empirically in two-stage model and parametrically in joint model); HS=High school. Boldface denotes CIs that exclude 0.
