I guess I’m missing something here. I thought they used the data from each rider/patient they dealt with.
That may be imperfect, for example we don’t have any data on the types of crashes, but I would be hesitant to 100% dismiss it based on the fact that they only measured those incidents.
I’m having a hard time saying that this is critically flawed to the point of being if zero use. But I’m not a statistician.
Study data does seem to be lacking in the ounkci domain, we had a good discussion on that in this topic
