ICD, International classification of diseases and related health problems; NA, not applicable.

^a These ICD-based definitions of external causes of death were developed by the injury expert group of the 2005 Global Burden of Diseases, Injuries and Risk Factors Study.¹⁰

^b There are also ICD codes outside the injury chapter that can include injury deaths. We used ICD-10 codes R95–R99 and ICD-9 codes 797–799 for the broadest unspecified cause-of-death category.

^c ICD-9 does not distinguish between the riders and occupants of motorized two- and three-wheeler vehicles (i.e. codes 3 and 4).

^d ICD-9 does not distinguish between occupants of different four-wheeled vehicles (codes 5–8).

^e Poisoning due to pesticides is included with other poisoning in ICD-9 (code 44)
