Table 8. AIC for minimal models containing dose measured as (i) the number of worms received and (ii) the worm exposure time, as explanatory variables for the measured immune parameters.
Immune parameter | Number of worms* | Worm exposure time* |
MLN IL4 | 238.8 | 241.4 |
Spleen IL4 | 60.8 | 60.3 |
MLN IL13 | 248.4 | 246.2 |
Spleen IL13 | 115.8 | 115.8 |
MLN IFNγ | 255.6 | 255.7 |
Spleen IFNγ | 247.5 | 247.5 |
IgA | 115.9 | 114.3 |
IgE | 282.1 | 283.9 |
IgG1 | 147.3 | 123.6 |
IgG2a | 53.3 | 47.8 |
IgG2b | 104.3 | 104.3 |
RMCPII | 232.0 | 245.7 |
Smaller AIC values indicate a more parsimonious model. Shown in bold is where minimal models for number of worms versus worm exposure time differ by at least 2 AIC units.
