Reference intervals: how they are constructed and why one in twenty flags — does this… Replied, post #22 · Clinical › Bloodwork · 26 Jul 2026 · 25 likes Same experience here, different supplier, so it is at least not unique to one of them.
[2026 update] Interpreting a result that disagrees with the supplier's certificate Replied, post #118 · Sourcing › Independent verification · 24 Jul 2026 · 0 likes Coming back to post #116, because the follow-up matters more than the original answer. My experience of Interpreting a result contradicts the reply above. I am posting…
[2026 update] Antibiotics and a course of something with delayed emptying Replied, post #74 · Practice › Interactions · 22 Jul 2026 · 11 likes The failure mode on Antibiotics is boring rather than dramatic. It is almost always the step everyone assumes was done correctly because it is too simple to get wrong.
Primary endpoint hierarchies and why order matters — one year on Replied, post #53 · Evidence › Trials · 20 Jul 2026 · 25 likes Coming back to post #51, because the follow-up matters more than the original answer. Dropout is information: high dropout rates can indicate tolerability problems or…
Coming back to: When a red flag was a misunderstanding, and the retraction Replied, post #10 · Sourcing › Red flags · 16 Jul 2026 · 0 likes Where somebody posts a concern, ask what would resolve it before arguing about it. Half of these threads end with a document nobody had asked for.
Common supplements people ask about, assessed one at a time Replied, post #37 · Practice › Interactions · 12 Jul 2026 · 0 likes Bookmarking this. I will come back when I have something worth adding.
How much context is too much context in a first post? Replied, post #40 · Start Here › How to Ask · 7 Jul 2026 · 0 likes Coming back to post #38, because the follow-up matters more than the original answer. A question about somebody else's post should be a reply to that post, not a new…
About the Mass spectrometry category Replied, post #6 · Analytics › Mass spectrometry · 4 Jul 2026 · 0 likes Adding a note of thanks rather than an opinion. I did not know most of that.
Journal club: indirect comparison between two programmes, defended and attacked Replied, post #105 · Evidence › Journal club · 3 Jul 2026 · 9 likes The bit of indirect comparison that nobody enjoys is that the answer changes depending on what you are trying to decide with it. Say what the decision is and the thread…
[2026 update] Antibiotics and a course of something with delayed emptying Replied, post #7 · Practice › Interactions · 3 Jul 2026 · 0 likes A supplement is a drug for interaction purposes, and the fact that it is sold without a prescription tells you nothing about whether it interacts. The paperwork is…
Why a glucagon receptor agonist in a weight-loss compound is not a contradiction Replied, post #18 · Compounds › Retatrutide · 29 Jun 2026 · 0 likes Worth separating two things that post #14 runs together. Heart rate increased in a dose-dependent way in the phase 2 work. That is not a footnote — it is one of the…
Tesamorelin has an approved indication — what that changes about the evidence Replied, post #19 · Compounds › Secretagogues & GH axis · 27 Jun 2026 · 0 likes Speaking only to tesamorelin as I have actually seen it, rather than as it is usually described: the effect is real, it is smaller than the thread suggests, and the…
