Journal club: SUSTAIN 6 and its retinopathy signal Replied, post #120 · Evidence › Journal club · 26 Jul 2026 · 9 likes Two things can be true about SUSTAIN 6 at once: the mechanism is plausible and the evidence for the size of the effect is thin. Most of the argument here is people…
What consumer-accessible tests can and cannot determine — a second dataset Replied, post #125 · Analytics › Home & field testing · 26 Jul 2026 · 6 likes Picking up post #122: that is the part I would want checked first. Ultraviolet absorbance at 280 nanometres estimates concentration for peptides containing aromatic…
Insurance and replacement policies, compared Replied, post #111 · Sourcing › Logistics · 23 Jul 2026 · 0 likes Narrowing post #110, because the general version has more than one answer. Adding the boring version of insurance and replacement policies, because the interesting…

What a reversed-phase purity number actually is Replied, post #53 · Analytics › HPLC & UHPLC · 14 Jul 2026 · 8 likes Particle size and column dimensions determine what resolution is achievable at all. A 5 micrometre 250 millimetre column and a sub-2 micrometre 100 millimetre column…
Pooling trials with different estimands Replied, post #77 · Evidence › Meta-analyses · 7 Jul 2026 · 0 likes Answering the question post #73 raises rather than the one it answers. Study quality and weighting: some meta-analyses weight all studies equally; others weight by…
Revisiting: What pooling buys you and what it destroys Replied, post #80 · Evidence › Meta-analyses · 5 Jul 2026 · 7 likes Adding the measurement that post #77 says would settle it. Adding what did not work for me on pooling buys, since the failures never get written up and they are half…
Semaglutide and gastric emptying — the mechanism behind most of the side-effect profile Replied, post #89 · Compounds › Semaglutide · 3 Jul 2026 · 12 likes Since semaglutide and gastric emptying keeps coming up, it should probably be a maintained page rather than a recurring thread. I am happy to draft it if someone with…
