      I generally agree with you about the limitations (my thread about this here: https://twitter.com/hwitteman/status/993659878039261184 …). My view on the Facebook group is that it’s just another way to do snowball sampling. I’m not sure why it deserves particular censure?

      Very interesting results. Great to see an observational study of this. Would love to see trials, especially factorial hi/med/lo carb x closed loop/no closed loop (or possibly CGM/no CGM). https://twitter.com/anahadoconnor/status/993344628043612160 …

      For a qualitative sample I'd be on the same page but it strikes me as a very poor strategy to get a sample for a quantitative piece of work

      How would you sample for a rare condition or a rarely-used approach? I don't know, I see plenty of problems here (huge potential for selection bias) but when you have a community of people doing XYZ and you want to study the effects of XYZ, it seems a reasonable place to start.

      I feel like online surveys give you scope to find all sorts of people more easily, choosing to only recruit from one small FB group means you're just looking for confirmatory opinions rather than actually studying anything

      To me it seems like the researchers just wanted something they could put in the paper to get funding for some more research rather than actually trying to answer any questions at all

      I think you may benefit from some content/context knowledge here. As far as I know there's really only the one community of people committed to this approach, and they mostly congregate on that Facebook group. I don't know where else one would seek participants.

      There's only one group of people trying ultra-low-carb diets for T1D? I find that unlikely. It might not be this specific diet, but I imagine there are any number of communities doing similar things

      Do you study or participate in T1D communities?

      Study. There are a couple of people on my team who are T1 but I am not one of them. I'm more population-focused, though. The qualitative/community stuff is mostly colleagues

      Can you point me to some of your quantitative work on T1D communities?

      As I said, I'm not really involved in that side of research. I mostly look at population health

          So when I asked, “Do you study or participate in T1D communities?” the correct answer was “No.”

          Well, I'm currently involved in a project looking at Indigenous diabetes communities in a specific region of Sydney, split into T1 and T2, but since the grant was only just approved it's early days
