Loose evidence and no evidence are different, and people overcorrect in both directions.

You have two changes at once here. You cannot attribute anything until one of them moves.

Reference ranges differ between labs, so comparing two reports is close to meaningless.

Filing early beats arguing later. And ask for the reference number, always. Tolerance was my main issue with a reclassified medicine too.

An inconclusive account is useful if it stops the next person mistaking a story for a controlled comparison.

A certificate of analysis answers one question and gets quoted as though it answers four.

Half of what people describe as tolerance is a change in the underlying condition, and the two need different answers.

Same here.
