Carryover and the ghost peak from last week's standard — what changed since Replied, post #103 · Analytics › HPLC & UHPLC · 3 Jul 2026 · 25 likes For anyone finding this later: the short answer on Carryover is that it depends on one thing, and the rest of the thread is people identifying which thing.

Follow-up: State-level differences that actually matter Replied, post #28 · Regional › North America · 5 Apr 2026 · 28 likes Say which country and which state or province. Regulatory position, availability and practical route can all differ within the same continent and frequently do.
Preprint servers and what screening they do — the long version Replied, post #9 · Evidence › Preprints · 28 Mar 2026 · 0 likes Narrowing post #6, because the general version has more than one answer. Where a preprint's numbers are the basis of a claim being repeated here, someone should check…

Muscle cramps: the ordinary causes before the exotic ones Replied, post #82 · Practice › Side effects · 20 Jan 2026 · 18 likes Two things can be true about muscle cramps at once: the mechanism is plausible and the evidence for the size of the effect is thin. Most of the argument here is people…

Aggregates and why a purity assay may miss them entirely Replied, post #11 · Analytics › Impurities & related substances · 16 Dec 2025 · 11 likes Post #10 answers the question as asked.

Tracking a preprint to publication: a worked example Replied, post #29 · Evidence › Preprints · 2 Dec 2025 · 0 likes Tracking a preprint is a good example of a question where the honest answer is boring and the interesting answers are unsupported. I would go with boring.

Price changes over 2025 and 2026, tabulated and dated — does this still hold? Replied, post #12 · Access › Pricing · 8 Nov 2025 · 14 likes Price changes has been discussed here with more heat than it deserves, mostly because two definitions have been in play the whole time.
Why the titration planner refuses to produce a schedule below a floor Replied, post #8 · Data & Tools › Calculators · 7 Nov 2025 · 0 likes Coming back to post #4, because the follow-up matters more than the original answer.

Tracking that stops updating and then resumes — the long version Replied, post #30 · Sourcing › Logistics · 26 Oct 2025 · 0 likes Peak periods and public holidays affect this more than any other factor and are entirely predictable in advance. That has held every time I have looked, which is not…

What pooling buys you and what it destroys Replied, post #6 · Evidence › Meta-analyses · 17 Aug 2025 · 7 likes Post #4 is the version of this I will quote in future. One addition. Individual participant data pooling is a much stronger design than aggregate pooling and is rare…
Revisiting: German, French and Dutch differences, compared Replied, post #56 · Regional › European Union · 9 Aug 2025 · 5 likes Careful with the language on German. "Not detected" and "not present" are different findings and the first is a statement about the method.

Regression to the mean in progress reports Replied, post #31 · Research Methods › Statistics · 11 Jul 2025 · 2 likes Answering the question post #29 raises rather than the one it answers. Worth stating the null on regression before we explain it: the observation may be nothing. That…
What a documentation review can and cannot tell you Replied, post #18 · Sourcing › Independent verification · 29 Jun 2025 · 4 likes Taking post #17 at face value and following it one step further. A record with four results over sixteen months is a thin record rather than a bad one, and the honest…
Repeatability versus intermediate precision Replied, post #88 · Analytics › Method validation · 28 Jun 2025 · 18 likes The reason repeatability versus intermediate precision is hard to answer is that the obvious measurement and the relevant quantity are not the same thing, and…
History of disordered eating and why it changes the conversation Replied, post #3 · Clinical › Special populations · 28 Jun 2025 · 6 likes One more thing on history of disordered eating that took me far too long to see: the two figures people quote are not measuring the same quantity.

Cost per milligram, computed honestly across formats — the long version Replied, post #121 · Access › Pricing · 31 May 2025 · 0 likes Landed cost including shipping, fees and currency conversion is what you actually pay, and quotes that look identical frequently are not. It took me longer than it…
Domestic fridge temperature mapping: a cheap experiment — what changed since Replied, post #110 · Devices › Cold chain · 25 May 2025 · 0 likes Recording arrival condition on ordinary deliveries is what makes the record useful.

Journal club: STEP 1 and the treatment-policy estimand — does this still hold? Replied, post #18 · Evidence › Journal club · 17 Apr 2025 · 4 likes STEP 1: I would want to see the raw numbers rather than the summary before agreeing. Summaries lose exactly the information that would settle this.
