All p-values for comparing firefighters vs. non-firefighters and also for comparing career firefighters vs. volunteer firefighters vs. non-firefighters are less than 0.05, i.e., statistically significant, except the following: SES % poverty level and cigarette use were not statistically significant by occupation: firefighters vs. non-firefighters (p > 0.05). Cigarette use was not statistically significant by occupation: career firefighters vs. volunteer firefighters vs. non-firefighters (p > 0.05).
