Summary (parameter estimates and standard errors) of the mixed-effects models assessing the relationship of group and time with frequency of reactive behaviors.a Differences from control animals are estimated from mixed-effects regression models fitted to the frequency of behaviors and adjusted for gender, day, and the interaction between group and day.
