Though statistically insignificant, complete resolution of baseline anemia was associated with gains in absolute CD4-cell count (difference = 27.4, 95% CI: −16.8, 71.5) whereas incomplete anemia resolution was associated with lower month 18 CD4 cell-count (difference = −34.6, 95% CI: −80, 20.9) relative to anemia free PLWHA. The gene discussed is CD4; the disease is anemia (phenotype).
