Coefficients derived from final multivariate model predicting weight change, accounting for effect modification by Interval.
| Difference in weight change (β) ± SE (P-value) | P-value for interaction term | ||
|---|---|---|---|
| Interval 1 | Interval 2 | ||
| Intercept | −2.7 ± 1.8 (.14) | 4.1 ± 0.9 (<.001) | 0.001 |
| CD4 <200 cells/μL (yes/no) | 3.5 ±1.5 (.03) | −3.0 ± 0.7 (<.001) | <0.001 |
| Adherence to HIV meds (Excellent/Very Good versus Good/Fair/Poor) | 3.0 ± 0.9 (.002) | −0.01 ± 0.7 (.98) | 0.01 |
| Nausea (yes/no) | 2.2 ± 0.8 (.006) | −1.3 ± 0.8 (.13) | 0.005 |
| Moderate/Heavy Drinker (yes/no) | −2.6 ± 1.0 (.02) | −0.02 ± 0.8 (.98) | 0.06 |
| Liquid supplements (yes/no) | 2.6 ± 1.0 (.01) | −1.3 ± 1.5 (.39) | 0.05 |
| Tobacco smoking | −1.2 ± 0.5 (.02) | 0.17 | |
Interaction term (Tobacco smoking ∗ Interval) was dropped from the final model due to nonsignificant P-value. Coefficient shown is from main effect of tobacco smoking only.
