Note. ZIP regression was used for medically attended injuries, negative binomial for minor injuries, and ZINB for close calls. eb = factor change (Long & Freese, 2006), and interpretation of this value is similar to that of odds ratios (i.e., for a unit change in variable x, the expected count changes by a factor of eb).
