Figure 4. Cohort size considerations.

Figure 4

PBMC from the entire cohort (n=391) (239 CMV+, grey closed squares; 152 CMV−, black open squares, A.) or its subsets of 80 (40 CMV+ and 40 CMV− donors, B) or 120 (80 + another 40 weighed; total 73 CMV+ and 47 CMV−, C) individuals were analyzed for the possible impact of CMV upon the decline of naive T cells plotted against age. Note the changes in significance (p value by regression analysis) as a consequence of cohort size.
