Weaknesses with a Meta-Analysis Approach to Assessing Cycle Helmets

Cycle helmets are a contentious issue which stems from evidence both for and against their use and the negative effects from when legislation is imposed, which has led to fines for non-wearers, some people cycling less or stopping and health implications. A meta-analysis by Olivier and Creighton includes reports that compare the proportion of head injuries or other injuries for wearer vs non-wearers. Weaknesses in this approach stem from the combined effect of issues which affect both the accident rate and head injury rate for helmeted vs non-helmeted or not fully being able to evaluate the differences that occur. The meta-analysis claims that helmet use is associated with odds reductions of 51% for head injury, 69% for serious head injury, 33% for face injury and 65% for fatal head injury. When examined in detail, all were found to be unreliable claims due to weaknesses of the supporting evidence and methodology.
