Summary of Hierarchical Regressions to Determine the Impact of HIV-Associated Encoding and Retrieval Deficits on Long-Delay Free-Recall Across HAART Adherence Groups

	Model 1		Model 2
Variable	β	SEβ	β	SE β
Good HAART adherers (≥90%)
Encoding-Deficit Index	−0.71	0.13	−0.59	0.13
Retrieval-Deficit Index			−0.41	0.17
R 2	0.50		0.59
F (change in R2)	31.30**		6.08*
Poor HAART adherers (<90%)
Encoding-Deficit Index	−0.67	0.12	−0.48	0.11
Retrieval-Deficit Index			−0.53	0.11
R 2	0.43		0.65
F (change in R2)	29.84**		23.95**

Raw values were used for regression analysis; the retrieval difficulties index was not corrected for acquisition.

HIV: human immunodeficiency virus-1; HAART: highly-active antiretroviral therapy; SE: standard error.
