It never ceases to amaze when “experts” don’t understand basics.
Commenting on this BBC article about the World Health Organization decision to link processed meat with cancer, an expert downplays the the link because the “size of the effect is relatively small” — meaning that the epidemiological correlations are weak.
NO! When the size of an epidemiologic correlation is small (i.e., relative risks on the order of 2.0 and smaller), that means that there is no credible evidence that there is even an effect at all. This is basic epidemiology. Shocking that so-called “experts” don’t understand this.
