Table 2.

Description and results of model comparison for the three models considered.

Model Predictors Intraclass Correlation Coefficient log likelihood
Null Sex, age, shared 9-month effect, random intercepts for individuals 0.23 32.94
Baseline Effects Same as Null, along with BioBehavioral Assessment measures 4.16*10^-10 43.07
Nine Months Effects Same as Baseline Effects, along with interaction of BioBehavioral Assessment measures and 9-month effect 0.24 55.44

log likelihood ratio comparisons: Baseline-vs-Null: 20.26, p<0.01; Nine-Months-vs-Baseline: 24.75, p<0.002
