Note. Estimates were based on logistic models for the sample of people aged 70 years and older that adjust for age, gender, proxy, proxy interacted with post-1996 indicator, and the socioeconomic factor under consideration; the models do not adjust for the other 2 socioeconomic factors simultaneously. The reference groups were as follows: 0–8 for education, lowest quartile for income, and “all other groups” for race/ethnicity.

^aStatistically significant trend relative to the trend for the reference group at the .10 level.

^bStatistically significant trend relative to the trend for the reference group at the .05 level.

^cStatistically significant trend relative to the trend for the reference group at the .01 level.

* P = .1; **P = .05; ***P = .01.
