Journal club: SUSTAIN 6 and its retinopathy signal Replied, post #80 · Evidence › Journal club · 18 Jul 2026 · 10 likes Since SUSTAIN 6 keeps coming up, it should probably be a maintained page rather than a recurring thread. I am happy to draft it if someone with more direct experience…

Why we ask for units every single time, with three examples of what goes wrong Replied, post #130 · Start Here › How to Ask · 15 Jul 2026 · 19 likes Avoid "any advice?" at the end.

An appeal that succeeded, with the letter structure — the long version Replied, post #131 · Access › Insurance & coverage · 21 Jun 2026 · 0 likes An observation about appeal that I cannot explain and am posting anyway, on the principle that unexplained observations are more useful public than private.

Reference intervals: how they are constructed and why one in twenty flags Replied, post #117 · Clinical › Bloodwork · 18 Jun 2026 · 7 likes If someone has run reference intervals properly I would rather read that than my own reconstruction of it. Posting mine only because the thread has gone quiet.

Micronutrient adequacy at low total intake Replied, post #88 · Nutrition & Training › Protein & intake · 13 Jun 2026 · 6 likes I will take the caveat as seriously as the claim, which is the point of putting it there.

Comparing prices across jurisdictions without misleading yourself Replied, post #61 · Access › Pricing · 10 Jun 2026 · 14 likes What would change my mind on comparing prices across jurisdictions is a second dataset collected by someone with no stake in the first. Until then I hold it loosely and…
