Table 2.
The paired Student's t-test assuming unequal variance was used to determine the statistical significance of enhanced T-cell activation as shown in Fig. 4
| T-cell population | P-value (overall) | P-value (PPD +ve) | P-value (PPD –ve) |
|---|---|---|---|
| CD4+ CD25+ | 0·05 | >0·05 | 0·05 |
| CD8+ CD25+ | 0·01 | >0·05 | 0·01 |
| CD4+ CD54+ | 0·01 | 0·05 | 0·05 |
| CD8+ CD54+ | 0·0001 | 0·01 | 0·05 |
| CD4+ CD71+ | 0·01 | 0·05 | >0·05 |
| CD8+ CD71+ | 0·001 | 0·05 | 0·01 |
BCG-exposed DC co-cultures were compared to TNF-α-exposed DC co-cultures at 96 hours. A P-value < 0·05 was taken to show a statistically significant increase in T-cell activation.
