It's far from one study that has found a link between red meat and heart disease.
Imagine a paper that proved 2+2=4 by surveying preschoolers and going with the majority vote. Correct conclusion, questionable methodology.
I simply wanted to point out that there is significant indications from other studies that red meat, and in particular processed red meat, is correlated with heart disease (and cancer).
In cardiology, an odds ratio of about 1.2, called tiny by the article, can actually be considered quite large in some circumstances. Very roughly speaking, it's about equivalent to your risk per ten years of age of developing heart failure, or per 20 mmHg of systolic blood pressure [1].
