Adjusted prevalence distribution and adjusted odds of alcohol- and gun-involved suicides, by state alcohol and gun policy score phenotypes from multinomial logistic regression model including interaction between alcohol and gun policy scores

^a Adjusted odds ratios compare the odds of the suicide category (columns in the table) for states with a APS – gun score combination vs. states with low scores on both the APS and gun score

^b Low policy scores are at the sample 25th percentile (40.9 for the APS score, 12 for the gun policy score), high policy scores are 10 points higher than the low score. Lower scores indicate less restrictive policy environments, whereas higher scores indicate more restrictive policy environments
