Descriptive statistics and summary (parameter estimates and standard errors) of the mixed-effects models assessing the relationship between group and frequency of behavior variables. Average group behaviors are based on observed frequency of behaviors. Differences from control groups are estimated from mixed-effects regression models fitted to the frequency of behaviors and adjusted for gender.
