Selection into a registry and what it does to the estimate — a second dataset Replied, post #28 · Evidence › Study critique · 23 Jul 2026 · 1 like Selection is well covered in the tag pages, and the older discussions are better than the recent ones because they were argued out properly.

Named, unnamed and unspecified impurities as regulatory categories — the long version Replied, post #93 · Analytics › Impurities & related substances · 19 Jul 2026 · 7 likes This follows post #92 rather than contradicting it.

Careful with the language on conditions. "Not detected" and "not present" are different findings…

[2026 update] Regional warehouse stock versus direct despatch Replied, post #125 · Sourcing › Logistics · 6 Jul 2026 · 5 likes Before the thread moves on from Regional warehouse stock versus direct — what is the sample size behind the claim? I am not being difficult; I have seen the same figure…

Pooling trials with different estimands Replied, post #45 · Evidence › Meta-analyses · 24 Jun 2026 · 24 likes Taking post #42 at face value and following it one step further. Study quality and weighting: some meta-analyses weight all studies equally; others weight by study size…

Carryover and the ghost peak from last week's standard — what changed since Replied, post #36 · Analytics › HPLC & UHPLC · 15 Jun 2026 · 0 likes Worth stating the null on Carryover before we explain it: the observation may be nothing.
