Table 1 GLMM (generalized linear mixed model with binomial error distribution and logit link function) to test the influence of elevation, migratory status (elevational migrant versus resident) and season (breeding versus non-breeding) as fixed effects on the probability of infection with Plasmodium spp., Haemoproteus spp., Leucocytozoon spp., total infections and mixed infections after controlling for host taxonomy as random effect

From: Do avian blood parasites influence hypoxia physiology in a high elevation environment?
