      27/n In this case, with a prevalence of ~35% for caffeine intake of 200mg or higher, the number of miscarriages attributable to this is: 0.35*(1-(1/1.28)) = 0.763 = ~76,300 miscarriages So, about a quarter of what's in this study

      28/n This actually makes perfect sense when you think about it. Remember, the ABSOLUTE risk increase of miscarriage for women who drink caffeine is pretty small - 1-2% - so it doesn't really make sense to say that up to a third of miscarriages are caused by caffeine

      30/n More broadly speaking, do we know that caffeine causes bad pregnancy outcomes? That is a VERY tricky question to answer

      31/n This narrative review argues yes, absolutely, and while most people would agree a LOT of caffeine is a problem, much previous research has said that small amounts are probably not so badpic.twitter.com/50siPcJ8HD

      32/n This narrative review argues that all such studies are the product of industry funding, which is not entirely untrue, but also doesn't really tell the whole story given that it disagrees with non-industry studies as wellpic.twitter.com/ynC0gKO1nj

      33/n Ultimately, reviews like this come down to opinions Do we think that Prof James is correct and caffeine is definitely bad? Well, maybe. It depends on your perspective I think

      34/n What we can't say is that this is new evidence, or even that we've proven anything here. It's one well-researched opinion that you may or may not agree with 🤷‍♂️

      35/n Anyway, regardless of what you think of the review, it's probably worth correcting the inaccurate table @BMJ_EBM

      36/n Also, for the record, I think the conclusions are pretty massively overstated, and also miss out a key part of recommendations which is the question of whether they'll be followed!pic.twitter.com/uPDQfv4aHI

      37/n I should also say that I thoroughly dislike opinion pieces and media attention like this The evidence hasn't changed, and quite frankly I think pregnant people have enough to worry about without the fear that a cup of coffee will cause a miscarriage

          That's exactly it. It's a gruelling enough experience without piling on more guilt, based on not very much.

          Fascinating studies showing fewer premature births (wondering about miscarriages) during lockdowns. What's your view on that? Was thinking about your point on stress (of which there's plenty while pregnant) and what the real (and not socially-induced) ranking of dangers is.

          Maybe if James had read 20 in stead of 40 studies he could have used the spare time to lear statistics. As it is his apparent innumeracy is a giant blaring red flag for me. If this paper is just his opinion, I’m now inclined to not give it much credence at all.

          As for the media picking up on the most eye-popping finding and running with that, that’s just life. Even if the journalist knew enough to spot the errors (they don’t), they would probably still run with it knowing full well that they have plausible deniability.

          And those who do or did or will miscarry have more than enough to deal with than hearing this and bashing themselves for having had that one cup of coffee during pregnancy...

          Thanks for this, though Twitter have done something to the web app that makes reading threads a pain - have to keep clicking on "additional replies".
