Table 1 Adjusted repeatability estimates for measured traits from the cortisol response test and rank index

From: Repeatability of endocrine traits and dominance rank in female guinea pigs

Response variable R (SE) 95% CI p
Baseline cortisol 0 (0.217) [0, 0.690] 0.5
Cortisol responsiveness (1 h) 0.635 (0.185) [0.229, 0.927] 0.019
Cortisol responsiveness (2 h) 0.764 (0.140) [0.433, 0.951] 0.002
Rank index 0.709 (0.156) [0.316, 0.935] 0.007
Change in body weight (absolute) 0.581 (0.212) [0.032, 0.906] 0.033
  1. Cortisol measurements (baseline and responsiveness) are adjusted for rank index, body weight, measurement (first or second), and housing group. Rank index and change in body weight are adjusted for the fixed effects listed in Table 2. Bold indicates significant values (p < 0.05). N = 24 observations, 12 individuals for all models
