  1. Codes with an * denote possible intentional injuries. Unlike Dunn and colleagues [3], we do not include codes for intentional injuries where these specify a means other than drug (e.g. firearm). We also do not include the injury codes for unspecified means; preliminary review established these were nearly all E988.9, and had little probability of relation with an endpoint.
