Estimate is the regression coefficient for each predictor and response variable. Bacteria killing ability (BKA) on day 36 was negatively related to CORT concentrations measured on day 14 post-hatch. CORT concentrations measured on day 14 were positively related to baseline CORT concentrations measured on day 60 post-hatch. Base=baseline, Anti-LPS Ab=specific antibodies to LPS, Clutch number=number of clutches parents had produced, Hp=haptoglobin, 12-Hr Hp=haptoglobin concentrations measured 12 hours after LPS challenge, Trt=treatment. Significant (p<0.05) effects are bolded.
