  1. Table 3 presents results of post hoc pair-wise comparisons performed for all significant interactions produced by linear mixed models that analyzed square-transformed late nestling growth, fledgling body mass and tarsus length, log-transformed LPS-specific immune response and log-transformed total antibody level in 5-day-old nestlings to separate the simple main effects involved in those interactions (by comparing the level of one factor within levels of another factor). Explanations of abbreviations: PBS-F/Control-B – nestlings of control females reared in control (non-manipulated) broods, PBS-F/Enlarged-B – nestlings of control females reared in enlarged broods, LPS-F/Control-B – nestlings of LPS-immunized females reared in control broods, LPS-F/Enlarged-B – nestlings of LPS-immunized females reared in enlarged broods, Female-N/Control-B – female nestlings reared in control broods, Female-N/Enlarged-B – female nestlings reared in enlarged broods and Male-N/Control-B – male nestlings reared in control broods, Male-N/Enlarged-B – male nestlings reared in enlarged broods
