Are YOU aware of any statistical study that ever recorded, measured or provides a clue on the type of equipment worn/not worn when cyclists were NOT injured "seriously" enough in bicycle accidents/falls/crashes to require a hospital visit?

I do not need to provide reference to "studies" or "specifics" that demonstrate the non-existence of surveys or studies on a subject; try Logic 101. If statistics, data, or credible studies exist about the type of equipment worn by people uninjured in bicycling accidents I am sure lots of the posters here would like to look and see what an intelligent analysis of the data might indicate.
