NOTE: Coefficients represent the average difference in the fatal drug poisoning rate (deaths per 100,000 population) during the period identified at the top of the column. NH Whites are the reference category. P-values represent the statistical significance of difference between each racial/ethnic group and NH Whites within each age- and sex-specific category.
