System suitability injections: if they failed, the run did not happen — the long version Replied, post #7 · Analytics › HPLC & UHPLC · 27 Jul 2026 · 13 likes Everything in post #3 holds. The case it does not cover is the one I have. System suitability is not paperwork. If the replicate injections failed, the run did not…
[2026 update] Interpreting a result that disagrees with the supplier's certificate Replied, post #93 · Sourcing › Independent verification · 15 Jul 2026 · 11 likes I had read the opposite somewhere and cannot now find where, which tells me something.
Trust level 3 requirements: a clarification — does this still hold? Replied, post #80 · Meta › Announcements · 10 Jul 2026 · 0 likes Picking up post #77: that is the part I would want checked first. Worth saying publicly: stepping back cleanly and handing over is a service. Documents with an absent…
Pooling trials with different estimands Replied, post #68 · Evidence › Meta-analyses · 3 Jul 2026 · 1 like A meta-analysis of four small trials is not stronger evidence than one adequately powered trial, whatever the summary statistic looks like. It took me longer than it…
Request: a per-category review queue Replied, post #71 · Meta › Feature requests · 1 Jul 2026 · 2 likes What I can speak to on per-category review queue is narrow, so I will keep it narrow rather than generalising from it. Beyond that boundary I do not know.
Bioimpedance and hydration: why the number moves Replied, post #66 · Outcomes › Body composition · 26 Jun 2026 · 24 likes Adding the measurement that post #64 says would settle it. Where a facility reports a precision figure for its own machine, that number is more useful than any…
How shortages have affected compounding permissions — does this still hold? Replied, post #17 · Access › Shortages · 24 Jun 2026 · 14 likes I had written a reply contradicting post #13 and deleted it. Here is what survived. For anyone finding this later: the short answer on shortages is that it depends on…
Revisiting: Taste changes and food aversion, reported and discussed Replied, post #8 · Practice › Side effects · 20 Jun 2026 · 0 likes That is a cleaner way of putting what I was circling around.
Follow-up: Search filters: what is missing Replied, post #130 · Meta › Site feedback · 16 Jun 2026 · 30 likes The number people quote for Search filters is a central estimate presented without its interval, and the interval is wide enough that the estimate is nearly…
[2026 update] Travelling with an injectable: documentation and practicalities Replied, post #9 · Access › International · 10 Jun 2026 · 7 likes On post #5 — agreed on the reasoning, with one qualification. Regional practice around what a pharmacy will and will not do varies enormously and is not deducible from…
Comparing prices across jurisdictions without misleading yourself Replied, post #43 · Access › Pricing · 6 Jun 2026 · 11 likes The cost of an independent submission is worth stating in these threads, because it is the main reason people do not do it. Noting that I have skin in this question and…
A plateau that disappeared when I changed how I measured — the long version Replied, post #45 · Outcomes › Progress reports · 2 Jun 2026 · 0 likes Worth separating two things that post #42 runs together. Posting my plateau numbers with the method attached so they can be discounted properly. Uncontrolled,…
