Body length of infected versus uninfected male and female hosts, 21 days post-exposure. P. ramosa induced gigantism in female D. magna but not in males (see Table 2 for details). Error bars show 95% confidence intervals. Stars in the legend represent significant differences based on t-test comparisons (P < 0.0001). The results for females remain significant (P < 0.01) when corrected for multiple testing. Note that P > 0.2 in all comparisons for males.
