[QUOTE=simonw7;998153Thanks I had not seen that. a lot of the discussion on the thread has been around whether or not hypothesis implied by bbc is borne out by the data given the sample size. the truth would be better represented by studies of data over a greater time period, including this paper (and presumably data has continued to be collected since this paper).

As I keep saying, the sample size is not small, it's large. It's in the millions. It's the number of male and female cyclists in London. What is small is the number of HGV deaths observed in this sample.
