Effect on cytokine genetic variants on parasite load.

As response variables we used only pathogens that infected 20–80% of hosts (S4 Table). β is parameter estimate for each contrast, R2 is partial coefficient of determination (effect size), χ2 and p-values are based on LR type III test. To control for multiple comparisons when testing for the effect of several genetic variants, we used conservative Bonferroni correction; for 10 genetic terms (SNPs) tested, the critical p-level corresponding to α = 0.05 was 0.005. Exact p-values of genetic terms significant after correction are given in bold. (PDF)
