Indeed. Grade C evidence is sufficient where more rigorous evidence is impossible/extremely hard to generate, regardless of the outcome of interest

If an intervention does not achieve its objective (outcome) do it anyway?

Not at all what I said. It is rare that you can delineate evidence so easily into yes/no on whether it works or not, which is where grading comes in

Gid, “Grade C evidence is sufficient ....regardless of the outcome of interest” It’s that last bit....”regardless of outcome”....why intervene then if the outcome doesn’t matter?

I am again confused. Obviously we care about the outcomes, the point is that grade C evidence can be applied to a diverse range of settings because it is an assessment of evidential backing

You and me both buddy! So if an intervention isn’t achieving its objective (eg ADG, Grade C) “just keep going bc Grade C is a good as we are ever going to get”?

Grade C? So you have a large, well-conducted systematic review of similarly rigorous observational trials demonstrating that populations with ADG are worse off than populations without? I'd be fascinated to see it. Seriously, sounds like an amazing study

Gid, I'm trying to clarify your statement. Observational studies aren't really a "trial"as there is no intervention such as an RCT. Nations who have national food guidelines (mostly OECD nations) were ahead in food-related chronic disease.pic.twitter.com/WOLBnbHwD0

ADG have not met their objective - not delivered the "outcomes" expected. Public health messaging on ADG haven't either (see evaluations Go for 2&5 inter alia). I've suggested "maybe Grade C evidence isn't enough to tell people what to eat" as ONE possible contributory factorpic.twitter.com/97WbJ8R9IT

You: Grade C is what we've always done Me: Grade C for ADG isn't achieving its objective You: Grade C is enough ...regardless of outcomes Me: Outcomes is the reason we intervene You: of course we care about outcomes Me: why keep going w intervention that isn't meeting objective

I have literally not once said that we should use Grade C evidence because it is "what we have always done" please stop using that strawman
