As ever, the best piece of writing (in my humble opinion) from over the weekend comes from the “Bad Science” blog. Ben Goldacre’s mind is hardwired for statistics, and this week he has turned it to the oft touted health benefits of smoking, and in particular, protection against Alzheimers. He discusses a recently published systematic review which – surprise surprise (and I’m sure I’m not spoiling it for anyone here – hey? what? smokings bad! You don’t say) – shows that the risk of alzheimers is increased in smokers. The really interesting part however, if you are into this sort of thing, is the analysis of papers where the researchers were associated with the Tobacco industry. Now that is a surprise I won’t spoil.
