Figure 4

Comparison of expression of highly and moderately expressed genes using DNA microarray and real time RT-PCR. Gene expression shown is that in relation to media, for BCG (A), and PPD (B). Microarray analysis involved 5 infants, whereas real time RT-PCR analysis involved these 5 infants plus an additional 10 infants (total n = 15). Box plots represent median plus 95^th, 75^th, 50^th and 25^th percentiles.
