CACE Model Estimates and Effect Sizes by Each Condition at 20th, 40th, 60th, and 80th Percentile of Exposure at 12 and 24 Months
CACE comparison | Condition | 20th percentile of exposure | 40th percentile of exposure | 60th percentile of exposure | 80th percentile of exposure |
---|---|---|---|---|---|
Baseline—12 months | Neutral | 0.39 (0.18) g = 0.27 (0.10–0.64) | 0.47 (0.19) g = 0.23 (−0.08–0.53) | 0.40 (0.20) g = 0.37 (−0.07–0.67) | 0.48 (0.29) g = 0.35 (−0.02–0.71) |
Incongruent | −0.08 (0.30) g = 0.02 (−0.35–0.39) | −0.10 (0.44) g = 0.14 (−0.16–0.44) | −0.56 (0.69) g = 0.23 (−0.08–0.52) | −1.61 (1.05) g = 0.35 (−0.01–0.72) | |
Baseline—24 months | Neutral | 0.04 (0.36) g = 0.08 (−0.29–0.44) | 0.61 (0.32) g = 0.19 (−0.11–0.49) | 0.77 (0.39) g = 0.21 (−0.09–0.51) | 0.44 (1.84) g = 0.29 (−0.08–0.65) |
Incongruent | −0.31 (0.31) g = −0.19 (−0.55-0.18) | −0.54 (0.44) g = 0.16 (−0.14–0.45) | −1.16 (0.73) g = 0.18 (−0.12–0.48) | −3.08 (1.11)* g = 0.34 (−0.03–0.71) |
Note: Top row of values are unstandardized CACE estimates (SE in parentheses). Negative CACE values indicate reductions in ISD (i.e., improvements in behavioral performance). g = Hedges’ g (standardized mean difference between compliers and noncompliers at each percentile level). Values in parentheses represent 95% confidence intervals. Positive effect sizes indicate greater improvement in the compliers.
