Analysis of variations of CD4⁺ T-cells stratified according to baseline quartiles by longitudinal analysis for repeated measurements. Longitudinal analysis for repeated measurements of changes of CD4⁺ T-cell number (cells/μL) from baseline is shown. Left panel: baseline quartiles values; right panel: annual changes by baseline quartiles. Data (n = 91) are presented as mean values with standard error. CD4⁺ T-cell quartiles at baseline: Q1 <493 (n = 23), Q2 493–600 (n = 24), Q3 601–734 (n = 22) and Q4 >734 (n = 22). The number of participants tested are as follows: year 1 n = 89, year 2 n = 59, year 3 n = 42, year 4 n = 36, year 5 n = 51, year 6 n = 75, year 7 n = 58, year 8+ n = 37. p-values assess the values at year 1–8 after immunization vs. baseline values. The analysis includes multiple measurements for each year.
