Table 4 Testosterone concentrations in relation to paternity loss

From: Parental care, loss of paternity and circulating levels of testosterone and corticosterone in a socially monogamous song bird

  Estimate Credible intervals (2.5%) Credible intervals (97.5%)
Intercept (no GnRH injection) 6.15 5.42 6.85
GnRH injection 0.9 0.56 1.25
Paternity loss −1.08 −1.79 −0.38
Stage 1.11 0.5 1.73
Brood −0.08 −0.58 0.44
Male age −0.36 −0.99 0.27
Paternity loss: stage 1.45 0.6 2.29
GnRH injection: stage 0.46 −0.06 0.96
  1. The second column shows the estimates which indicate the direction of the relationship. The third and fourth columns shows the credible intervals (Bayesian), if zero is not included within the credible intervals there is a ‘significant’ effect of this parameter on the dependent variable. Estimates of cofactors refer to differences from the intercept estimate, which represents no GnRH injection. ‘Significant’ differences are shown in bold.
