Results summary of the 29 candidate models for reintroduction mortality risk among 89 cohorts and 414 reintroduced black rhino.

Models are in descending order from most to least supported based on Akaike second-order Information Criteria (AICc). Leading models from previous analyses without interaction terms [9], [23 ] are italicized. The model without fixed effects is indicated in bold type. A ‘*’ indicates an interaction term in the regression between two variables and, by implication, predictors in interactions were also present additively in models (e.g., a*b refers to model including a+b+a*b as fixed effects).
