Can we make a link to the study mandatory pls?
Regarding the study, I think it’s plausible in a sense that they have a large, diverse sample and control for the things that you should control for but what I always miss in medical papers is a more sophisticated quantitative part. It might be somewhere where I just didn’t see it because I’m not from the field but I don’t really understand their mathematical model that has led to these findings, nor do I understand how to interpret these findings independently.
Vegetarian diets and cancer risk: pooled analysis of 1.8 million women and men in nine prospective studies on three continents - British Journal of Cancer
Vegetarian diets might influence cancer risk. We studied 1,645,555 meat eaters, 57,016 poultry eaters, 42,910 pescatarians, 63,147 vegetarians and 8849 vegans in 9 cohorts (UK, US, Taiwan, India). After a median 16 years follow-up, incident cancers were: 4504 mouth and pharynx, 1308 oesophagus (squamous cell), 2105 oesophagus (adenocarcinoma), 3578 stomach, 30,528 colorectum, 2970 liver, 8030 pancreas, 3077 lung (never smokers), 61,368 breast, 11,220 endometrium, 8076 ovary, 45,946 prostate, 7193 kidney, 6869 bladder, 11,651 non-Hodgkin lymphoma, 4658 multiple myeloma and 7306 leukaemia. Multivariable Cox regression was used to estimate cohort-specific hazard ratios (HRs) and 95% confidence intervals (CIs), and the results were combined using meta-analysis. Compared to meat eaters, poultry eaters had lower risk of prostate cancer (0.93, 0.88–0.98), pescatarians had lower risks of colorectal (0.85, 0.77–0.93), breast (0.93, 0.88–0.98) and kidney cancer (0.73, 0.58–0.93), vegetarians had lower risks of cancers of the pancreas (0.79, 0.65–0.97), breast (0.91, 0.86–0.97), prostate (0.88, 0.79–0.97), kidney (0.72, 0.57–0.92) and multiple myeloma (0.69, 0.51–0.93) but higher risk of squamous cell carcinoma of the oesophagus (1.93, 1.30–2.87), and vegans had higher risk of colorectal cancer (1.40, 1.12–1.75). Vegetarian diets might influence risk for several cancers. The generalisability should be considered cautiously.
porcoesphinoI went to upvote for the link but I’m pretty luke warm on the rest of the comment so didn’t.
Care to elaborate? Upvotes / downvotes are meaningless but if you have objections to the way I see it I might learn something and I mean that.
Adding the link and asking for that to mandatory is a comment / action I really want to promote, so I would usually upvote.
The rest of the comment I don’t really understand, so I didn’t upvote because I could be promoting a bunch of things I don’t understand or are wrong / misleading.
Since the first part was important, but your comment made multiple distinct points, I added my own comment to clarify what I thought was good.
No idea how I got all the downvotes for that but 🤷♂️
