In 1958, the UK licensed a drug for treating morning sickness. It worked very well. The studies all showed that pregnant women suffering from morning sickness received much relief with the drug. Three years later it was withdrawn, but not … Continue reading
The reason I pick up the bicycle helmet theme again this week is that the BMJ is running a sidebar poll of their readers (or, more accurately, of cycling tweeters and recipients of Robert Davis’s emails ), asking whether it … Continue reading
Some months ago I left a series on bicycle helmets hanging while I got distracted with other things. We had looked at what the best evidence for the efficacy of helmets in preventing injury in the event of a crash … Continue reading
The doctor’s representatives BMA and the “Road Safety” charity Brake both say “yes”. The Automobile Association and the cyclists say “no”. They can’t both be right. Unless the answer is “yes and no”. Find out how that could be so, … Continue reading
A good review of a medical intervention starts by explaining the population being studied. The Cochrane review of helmets for preventing head injuries in bicyclists explains that its population is the set of bicyclists who sustained an injury that was … Continue reading
In rare events like bicyclist injuries, odds ratios can be used as an approximation of relative risk: that is, how much a medical intervention changes the risk of a specific outcome. An odds ratio of 0.3 is interpreted as a … Continue reading
According to the Cochrane Collaboration — the source that most doctors will go to for their summary of the evidence — it is five studies from the 1980s and 1990s. Continue reading at At War With The Motorist…
I know a lot of you find the whole helmets thing — whether they “help” or “work” or not — tiresome and unimportant. Well tough. Bicycle helmets are a medical intervention — a special kind of medical intervention — and … Continue reading
