But it would seem to be utterly vital to determine the head injury rate wouldn't it? No point counting absolute numbers of injuries without exposure data. It's like saying the road toll now is higher than in 1955, without noting the number of cars on the road.... Zebee |

Zebee The original post simply suggests that *according to the Cochrane guidelines* the data isn't available. They're not suggesting that counting numbers out of context would be a good alternative... ali -- alison_b |

FWIW the oft-referred to correlation of helmet law intro and supposed corresponding drop in riding would seem to be utter bollox. The stats that i have seen show the same drop in riding for the 2-3 years prior. IE the die was set before the law's intro. I ain't personally advocating use or not, just saying drop in numbers wasn't due to helmet laws. Oh crap. i just entered a helmet-debate... -- flyingdutch |

Be interesting to see if anyone does a head injury rate vs participation vs helmet use rate won't it... Dunno why you wouldn't call them cyclists. They are riding bicycles after all. Can't exclude them just because you don't agree with their safety choices. Zebee |

Never mind the number of cars on the road. In 1964 the road toll in WA topped 400. Now the gov't is screaming at us and doubling demerit points and fines because the road toll is nearly 200, up from 180 the previous year. Theo |

I was riding to work in 1961 as were a lot of other people, never saw anyone with a helmet, and my mind didn't boggle at all. Theo |
