Probability of ending an association: output of the Cox proportional hazard mixed model for the total number of (known) days in association by the type of association partner, study site, age of the dependent offspring (years), and zFAI (χ27 = 28.80, P = 0.0002, N = 625 associations of which 426 with known end, of 21 female identities and 167 FPs). All fixed effects with P < 0.05 are indicated in bold
