Unstandardized coefficients (and 99% confidence intervals) relating T2-T1 difference to age and to the T1-T2 interval in the total sample of 2,367 participants

Note:

p<.01.

The coefficients for age represent differences in T2-T1 difference for each year of age, and those for the T1-T2 interval correspond to T2-T1 differences for each year of T1-T2 interval. The numbers in parentheses are the lower and upper values for the 99% confidence interval. Sample sizes ranged from 2,600 to 2,637.
