Seven-day rolling means and why weekly readings mislead Replied, post #104 · Outcomes › Progress reports · 25 Jul 2026 · 0 likes Agreed, and I will stop repeating the version of this I had been repeating.

What consumer-accessible tests can and cannot determine — a second dataset Replied, post #119 · Analytics › Home & field testing · 24 Jul 2026 · 0 likes Post #117 put the caveat in the right place and I want to underline it. On consumer-accessible tests, I would rather understate and be corrected upward than overstate…

What a reversed-phase purity number actually is Replied, post #86 · Analytics › HPLC & UHPLC · 23 Jul 2026 · 0 likes Post #84 answers the question as asked. The question underneath it is different. System suitability is not paperwork. If the replicate injections failed, the run did…

What a certificate commits its issuer to Replied, post #78 · Analytics › COA interpretation · 22 Jul 2026 · 13 likes "Not less than 98 per cent" is a specification. "98.3 per cent" is a result. A certificate carrying only the first has not told you what was measured.

Coming back to: A structured critique template this community uses Replied, post #63 · Evidence › Study critique · 19 Jul 2026 · 0 likes Filing a mild objection to the consensus on structured critique template. Mild because I might be wrong; an objection because nobody has addressed the case that does…

Aggregate verification data across the directory, with caveats Replied, post #50 · Sourcing › Independent verification · 16 Jul 2026 · 1 like I read post #48 twice before replying, because I had assumed the opposite. The record shows what was measured. Everything beyond that is inference and this site tries…

Follow-up: Search filters: what is missing Replied, post #139 · Meta › Site feedback · 25 Jun 2026 · 1 like Thank you for the correction. I would rather find out here than later.

Forced degradation studies: designing one that is informative Replied, post #83 · Analytics › Method validation · 24 Jun 2026 · 24 likes Narrowing post #80, because the general version has more than one answer. Specificity: the method can distinguish the intended compound from related impurities and…

Revisiting: What pooling buys you and what it destroys Replied, post #64 · Evidence › Meta-analyses · 22 Jun 2026 · 18 likes Individual participant data pooling is a much stronger design than aggregate pooling and is rare because it requires cooperation rather than a search.

What I would want from a home test that does not exist yet — what changed since Replied, post #49 · Analytics › Home & field testing · 10 Jun 2026 · 0 likes The arithmetic in post #46 is right; the assumption feeding it is the part to check. A test that gives a yes or no on the presence of peptide bonds is answering a…

A widely repeated interaction claim that turns out to be unsupported — what changed since Replied, post #60 · Practice › Interactions · 8 Jun 2026 · 0 likes Insulin and sulfonylureas are the interaction that the labelling in this class flags most explicitly, because the risk is additive glucose lowering. That is a…

A reconstituted vial's beyond-use date and the reasoning behind common figures Replied, post #62 · Practice › Storage & stability · 6 Jun 2026 · 0 likes Where I part company with post #60, and it is a narrow parting. Vial integrity: once a vial is entered with a needle repeatedly, the rubber closure degrades and the…
