We began with all individuals registered in Sweden on December 31, 2011, and excluded children, those with a cancer diagnosis, a pain diagnosis, or a previous substance use disorder diagnosis during 2010, as well as a small number of individuals with missing sociodemographic data.

Absolute risk of opioid prescription receipt for intersectional strata.
Absolute risk of opioid prescription receipt and 95% Credible Intervals (CI) by intersectional strata for individuals aged 18 years or more residing in Sweden from January 1, 2010 to December 31, 2011. Exact numerical values for each stratum are presented in S1 and S2 Tables.

Discriminatory accuracy of intersectional strata.
ROC curve analysis obtained in the simple intersectional model 1, quantifying the discriminatory accuracy of the intersectional strata for classifying individuals according to opioid prescription receipt.

Absolute risk due to interaction.
Absolute risk due to interaction (ARI) obtained in the intersectional interaction model 3 in relation to opioid prescription receipt during 2011 for adults residing in Sweden on December 31, 2010, by intersectional strata. Point estimates are ARIs and 95% Credible Intervals (CI). Exact numerical values for each stratum are presented in S1 and S2 Tables.

Absolute risk due to interaction: Total and main effects.
Presentation of the absolute risk due to interaction (ARI) calculated by subtracting the absolute risk due to the main effects of the variables that define the intersectional strata from the total stratum specific absolute risk. Exact numerical values for each stratum are presented in S2 Table.
