  1. This table presents a synthesis of the main statistical data. In the left column, percents were calculated according to the total number of deaths (1′122 deaths). In the four right columns, percents are related to the total number of cases from the corresponding category except the last column (percentages calculated for autopsied cases). The group “transport accidents” includes deaths that may derive from a cardiac cause, or a SCD resulting in loss of control of the vehicle. Drowning/submersions are normally classified in the group “other external causes of mortality”. The column on the very right includes those cases with feedback from the autopsy results, enabling confirmation of the cause of death (data received from IUMSP). It is possible that the percentage of autopsies with a confirmed cause of death could be higher if the autopsy results were neither not available nor considered during the codification process.
