The Standardized Mortality Ratio (SMR) of the total participants is the ratio between the observed number of deaths in the study population and the number of deaths that would be expected, based on the age- and sex-specific rates in the U.S. population in 2013 and the age and sex distribution of the study population. SMRs stratified by age at first diagnosis of OUD, mental disorder diagnosis, other drug diagnosis, and chronic pain are also calculated in this way.
The SMR of each gender is the ratio between the observed deaths of that gender in the study population and the number of deaths that would be expected, based on the age- and sex-specific rates in the U.S. population in 2013 and the age and sex distribution of the study population.
The SMR of each race/ethnicity is the ratio between the observed deaths of that race/ethnicity in the study population and the number of deaths that would be expected, based on the age-, sex-, and race/ethnicity-specific rates in the U.S. population in 2013 and the age, sex, and race/ethnicity distribution of the study population.
