If a systematic review finds only small, poorly-done studies on a topic but they have mostly null results should it conclude #EpiTwitter

And if we always call for more research, where does that end? Where is the cutoff between not an answer and an answer?

Also, should note - I'm not saying that calling for no more studies means that we think the question is closed, just that it doesn't seem worth pursuing with more research

You see i see a pilot study as a way to see if they work - ie are truly feasible to roll out on larger scale. I don’t think small poorly done studies would adequately answer a question to confidently say “well that’s that then!”

That's definitely true, but I'm thinking of the opposite - if we have a bunch of small studies indicating no effect, taking into account publication bias, is there a rationale for conducting more research?
