The authors report no conflicts of interest. None of the members of the GBD Injury Expert Group derive any salary support from the GBD project. However, several members have ongoing funded research in closely associated areas. KB, SS, JA and P-HY are supported by a grant from the World Bank Global Road Safety Facility, but this funder has played no role in the study design, data analysis, decision to publish or preparation of the manuscript. Ethical approval is not required. Please note that the database contains tabulated results and cannot be used to identify individuals.
