Following on from Dr.ReproEndo — and this may be the naive question:

How long did you give it before you decided it was working?

Careful with the causal language. Two things moving together in a period when five things changed is not a mechanism, and stating it as one makes the thread less useful to somebody reading it later.

Agreed, and the size of the effect matters as much as its existence. Something real and small gets treated here as though it were real and decisive.

Adding the clinical framing, because it changes how the question reads. If two explanations both fit, the useful question is which one predicts something the other does not. That is answerable; arguing about which sounds more plausible is not.
