Immortal time bias in a claims-database study — one year on Replied, post #36 · Evidence › Study critique · 21 Jul 2026 · 0 likes Per-protocol and intention-to-treat analyses answer different questions and neither is the honest one by default. Reporting both is the practice worth insisting on.

Seven-day rolling means and why weekly readings mislead Replied, post #56 · Outcomes › Progress reports · 18 Jul 2026 · 0 likes Seven-day rolling has been discussed here with more heat than it deserves, mostly because two definitions have been in play the whole time.

Why the timeline is on the right and not the left — what changed since Replied, post #76 · Meta › Site feedback · 17 Jul 2026 · 0 likes On post #75 — agreed on the reasoning, with one qualification. What would change my mind on timeline is a second dataset collected by someone with no stake in the…

A site rotation scheme that is easy enough to actually follow Replied, post #117 · Practice › Administration · 17 Jul 2026 · 16 likes This follows post #114 rather than contradicting it. If you have to inject at a different time of day than usual, that is a much smaller perturbation than it feels for…

What to bring: records that a clinician can actually use Replied, post #3 · Clinical › Prescriber conversations · 16 Jul 2026 · 11 likes Adding the measurement that post #2 says would settle it.

Follow-up: UK access routes, dated and sourced Replied, post #12 · Regional › UK & Ireland · 16 Jul 2026 · 6 likes Post #11 is right about the mechanism and I think understates the practical bit. MHRA is the regulator. Licensed incretin analogues are prescription-only medicines. NHS…

[2026 update] Detection wavelength and why 214 nm and 280 nm disagree Replied, post #39 · Analytics › HPLC & UHPLC · 15 Jul 2026 · 1 like Carryover from a previous injection shows up as a small peak at the same retention time in a blank. A method report that includes a blank injection is telling you the…

Deletion sequences: expected mass shifts by residue — the long version Replied, post #12 · Analytics › Impurities & related substances · 15 Jul 2026 · 0 likes That is the distinction I keep failing to hold on to. Written down now.

Semaglutide and alcohol: what is actually documented Replied, post #16 · Compounds › Semaglutide · 13 Jul 2026 · 29 likes That is a cleaner way of putting what I was circling around.

Journal club: STEP 1 and the treatment-policy estimand — does this still hold? Replied, post #63 · Evidence › Journal club · 11 Jul 2026 · 2 likes The arithmetic in post #61 is right; the assumption feeding it is the part to check. The figures usually contain the finding and the text usually contains the…

Revisiting: Why the absence of controlled human data on BPC-157 matters more than people… Replied, post #20 · Compounds › Repair & healing peptides · 8 Jul 2026 · 16 likes I had written a reply contradicting post #16 and deleted it. Here is what survived. BPC-157's published evidence is overwhelmingly preclinical and mostly rodent. That…
