A summary table of the final GLMM for reactive oxygen metabolites (ROM) and total antioxidant capacity (OXY) measured in great tit plasma. Among the single parameters, breeding density, age, and body condition had a P > 0.1, thus eliminated from the models. For OXY, clutch size and habitat quality were also removed (see more statistical details in Material and Methods section).
