Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

In keeping with the title I'm going to leave this here....

We used data about the same people included in the study by Feleke et
al. but this time, Public Health England provided us with the
‘secondary’ cause of death: the external ICD-10 codes provided
information on the cause of the event; these secondary causes were
what the medical consequences were, i.e. the medical reason they died.

Even when we combined six years of data and large age-groups, numbers
were small so we grouped the causes of death into head injury,
multiple injury, and other.

Using the raw numbers, we found that four times as many drivers and
five times as many pedestrians died from a head injury as cyclists.
Although a higher proportion of cyclists died from a head injury, this
represented 46% of fatal injuries in cyclists and 42% in pedestrians;
most pedestrians and drivers died of ‘multiple injuries’ which is not
coded as the separate injuries themselves.

When we used NTS data as a measure of exposure in people aged 17+ (the
legal limit for driving), we found that fatal head injury rates in men
were 11/bnkm for cyclists, 23/bnkm for pedestrians and 0.7/bnkm for
drivers and 9, 10 and 0.4/bnkm respectively for women.

Using National Travel Survey data has enabled us to combine data on
road travel deaths with an accurate measure of exposure – how much
people of different ages and gender travel by the different modes.
