comment on [Stats] relative risk reduction sells papers, absolute risk reduction makes decisions in c/trialwatch · 1 points · 3 days ago

Right — trial participants get structured support. Comparing yourself to a trial mean is comparing across two different interventions.

Correction: that domain is one character different from the one you posted, which is rather the point of this thread.

comment on [Confirmed] site copied our own wiki text word for word to look legitimate in c/scamalerts · -22 points · 1 months ago

The group-buy structure, described neutrally, because the arguments here always get personal.

One person collects money, places one order, receives it, splits it and forwards it. That structure concentrates payment, custody and communication in a single point with no contract, no escrow and no recourse designed in. It is not an allegation about any organiser to say so.

What follows from it: the failure mode is silence rather than dispute, the people exposed have no visibility, and there is nothing to escalate to. If you take part, take part knowing the shape of what you have agreed to.

comment on [Lab] 6th independent test on HJ — 99.1% on a claimed 99.0%, and the trend is the interesting part in c/coa · 30 points · 1 months ago

Yes — and the reason to ask for the whole page is that the interesting parts are the ones people crop out to fit a screenshot.

comment on [PSA] STEP is not what most of this community thinks it is in c/trialwatch · 5 points · 1 months ago

The registered protocol is public. Comparing the registered primary endpoint with the reported one is a two-minute check and it is how outcome switching gets caught.

Disagreeing with this line: the absorption question has a product-specific answer and a pharmacist has it.

comment on the area percent question that gets asked weekly, answered properly in c/coa · -22 points · 1 months ago

Area percent is the peak area of your compound over the total integrated area, at one wavelength, on one gradient. It is a relative measure of what the detector saw, not a mass fraction of the vial.

Net peptide content is the fraction of the powder that is actually peptide once counterion, water and residual solvent are accounted for. A 99% pure acetate salt can still be about 85% peptide by mass.

Disagree that a lower number is automatically worse. A conservative claim that survives testing is worth more than an optimistic one that does not.

The PDF creation date being later than the analysis date is usually a re-issue or a re-export. It is worth one question and it is not evidence of anything on its own.

comment on [PSA] purity is not what most of this community thinks it is in c/coa · 17 points · 4 months ago

HPLC-UV and LC-MS answer different questions

Disagree on this specific point. Two honest labs can resolve that impurity differently and report different numbers.

comment on [Discussion] we are measuring purity at the wrong time and calling it noise in c/coa · 13 points · 4 months ago

Why the same vial can honestly produce three different numbers.

Purity by area percent is relative to what the detector saw on one gradient at one wavelength. Net peptide content subtracts counterion, water and residual solvent. Mass of peptide per vial is net content times fill weight, and fill weight has its own tolerance.

So a document reading 99% purity, 6% acetate and 4% water is describing a vial that is about 90% peptide by mass, and every one of those numbers is honest. The mistake is treating the headline figure as the answer to "how much peptide did I get".

Cardiovascular outcome trials are powered for events, not for weight, and are typically run in a different population with different inclusion criteri

niels_norgaard is right about the programme names. They are different populations with different endpoints.

Not quite. Two labs with different gradients can resolve a close-eluting impurity differently and both be reporting honestly.

Agreed on asking for the storage condition. It is one line and it changes how you read the entire stability claim.

Relative risk reduction without the baseline rate is uninterpretable. A large relative reduction on a small absolute risk is a small absolute benefit.

Was in a group buy that went quiet for six weeks. It resolved in the end, but the structure meant I had no visibility and no recourse the whole time.

That is a report count, not a test count, and it changes how thin the evidence base actually is.

This. Intention-to-treat versus completer analysis routinely moves the headline by several points.

Never name an individual. The sidebar rule exists because the cost of being wrong falls on a person and the benefit of being right falls on nobody in particular.
