Summary of recombination, X4 and viral load patterns. The X-axis shows the sampling times in months post seroconversion, while the Y-axis shows the proportion of recombinants (blue diamond shapes) and X4 (orange square shapes) sequences. The light green thick line at the bottom along the X-axis shows the start and duration of antiviral drug therapy. The vertical dashed line indicates the highest peak in viral load levels; the dark dotted vertical line indicates the second highest peak, and the light dotted line the third highest peak in viral load levels. Patient 1 had only two viral load peaks, with a peak defined as a high point before a decline or at the last study time point.
