Fig. 3.

Predicted future distribution of true CD4⁺ categories given current observed CD4⁺ category (from left to right: >500 cells/μl, 350–500, 200–350 and ≤ 200) for all patients (top row) and stratified by set-point viral load (second to fifth rows).

Shades of blue indicate true CD4⁺ category, from light blue for CD4⁺ > 500 cells/μl to dark blue for CD4⁺ ≤ 200 cells/μl; grey indicates death.
