  • Deletion sequences: expected mass shifts by residue — the long version Replied, post #18 · Analytics › Impurities & related substances · 21 Jul 2026 · 3 likes The documentation on Deletion sequences is better than this thread and I say that as someone who has posted in the thread.
  • Immortal time bias in a claims-database study — one year on Replied, post #34 · Evidence › Study critique · 20 Jul 2026 · 9 likes The arithmetic in post #32 is right; the assumption feeding it is the part to check. The pre-specified endpoint being a weaker proxy than you would like is a real…
  • How shortages have affected compounding permissions Replied, post #54 · Access › Shortages · 20 Jul 2026 · 3 likes Post #52 put the caveat in the right place and I want to underline it. Checked the shortages claim against the primary source this morning. It survives, with a narrower…
  • Journal club: STEP 1 and the treatment-policy estimand — does this still hold? Replied, post #69 · Evidence › Journal club · 18 Jul 2026 · 15 likes Taking post #68 at face value and following it one step further.

  • What a certificate commits its issuer to Replied, post #49 · Analytics › COA interpretation · 17 Jul 2026 · 31 likes A chromatogram supplied as a small image is legible for peak shape and not for baseline detail. That is enough to sanity-check an integration and not enough to…
  • Journal club: what we got wrong in an earlier session Replied, post #87 · Evidence › Journal club · 15 Jul 2026 · 0 likes Reading order that works for these sessions: registry entry, methods, baseline table, primary result, then abstract last. Reading the abstract first anchors everything…
  • 0.3 mL versus 0.5 mL versus 1 mL barrels: resolution matters Replied, post #105 · Devices › Syringes & needles · 13 Jul 2026 · 0 likes That is a cleaner way of putting what I was circling around.
  • Splitting an overlong document into two Replied, post #31 · Documentation › Wiki requests · 9 Jul 2026 · 30 likes Answering the question post #27 raises rather than the one it answers. One caution on splitting an overlong document: everything above assumes the underlying…
  • About the Oral incretins category Replied, post #5 · Compounds › Oral incretins · 8 Jul 2026 · 0 likes PIONEER programme is phase 3 for oral semaglutide. The trials cover multiple indications and durations. Reading them requires attention to which trial is which because…
  • How shortages have affected compounding permissions Replied, post #18 · Access › Shortages · 6 Jul 2026 · 11 likes An observation about shortages that I cannot explain and am posting anyway, on the principle that unexplained observations are more useful public than private.
  • Carryover and the ghost peak from last week's standard — what changed since Replied, post #100 · Analytics › HPLC & UHPLC · 3 Jul 2026 · 4 likes This is the first time the answer has come with its own limits attached. Appreciated.
  • Why chargeback is not the safety net people assume Replied, post #22 · Sourcing › Payments · 30 Jun 2026 · 0 likes Where I part company with post #19, and it is a narrow parting. The site does not carry prices, payment details or transaction routes, and questions asking for them…
