Clinical perspective, offered as context rather than as advice. Take it one variable at a time. Almost every unanswerable question in these threads is unanswerable because three things changed in the same fortnight, and no amount of subsequent argument can untangle them after the fact.

This matches mine closely enough to be worth saying so out loud. I had assumed I was the exception until I read this.

Moderator note: the sourcing question belongs in the vendor section and has been split out. Thread quality here is what the rules are for. Keep it up.

One concrete data point for the thread. One practical note: write down what you did and when, before you need it. Reconstructing a timeline from memory three months later is how people end up unable to answer the one question that would have resolved it.

One thing that is still open after Dr.PathRoch’s answer:

Was that from a primary source or from a summary of one?
