Decay of plasma virus. (A–D) Individual best fits for each ΔGY-controller (A) and ΔGY-non-controller (B) and population best fits for ΔGY-controllers (C) and ΔGY-non-controllers (D). Each decay phase is indicated by a color, with corresponding half-life indicated in respectively colored text. Each point is the mean of six technical replicates. Open circles represent values below the LOD of the assay (15 SIV RNA copies/ml), which is indicated by a horizontal dotted line. Gray shading represents 95% confidence bands. A vertical dotted line represents the date of ART initiation. Insert graph in D is a zoomed-in version of the main graph.
