Predictors with positive coefficients were identified as being positively related with the count outcome of injury, ie, for a one-unit increase in the identified variable, the likelihood of injury increases by the respective value, assuming all other variables are constant.
Predictors with negative coefficients were identified as being negatively related with the count outcome of injury, ie, for a one-unit increase in the identified variable, the likelihood of injury decreases by the respective value, assuming all other variables are constant.
