It doesn't really mean anything.
Its like showing a chart showing only seatbelt usage and fatalities.
You would have to make the assumption that usage would have made a difference in outcome.

"Helmeted rider traveling at high rate of speed collided with dump truck and died"

Well if he wasn't wearing a helmet then he would have lived!!!
