Why You Can Ignore That Pancreatic Cancer ‘Study’
Our study has some limitations. First, as a meta-analysis of observational studies, we cannot rule out that individual studies may have failed to control for potential confounders, which may introduce bias in an unpredictable direction. All studies controlled for age and smoking, but only a few studies adjusted for other potential confounders such as body mass index and history of diabetes. Another limitation is that our findings were likely to be affected by imprecise measurement of red and processed meat consumption and potential confounders.
Let me put that into plain English: Our findings are meaningless. The studies we analyzed were based on food-recall surveys that are notoriously inaccurate, and most of them didn’t control for body mass index or diabetes, which essentially means they didn’t control for intake of sugars and refined carbohydrates.
