Great post @apsmunro.bsky.social! Doing more is such a natural reaction. But even 'benign' interventions may likely be harmful when tested properly. I'm yet to know of a trial for sepsis where adding antibiotics has been beneficial (outside of TB where we do it to prevent emergence of resistance).

Why why why why do people cut and paste huge amounts of information between the Protocol, SAP, and assorted other documents. This is essentially expressing a huge preference toward inconsistent documentation and a desire to triple the workload of anyone working on any change to any document.

I think this issue is one of the most appealing aspects of Bayes. With Bayes the posterior distribution is the basis for inference, and it is invariant to the design.

Response adaptive randomization adjusts allocation probabilities over the course of a trial, based on accumulating data. RAR increases allocation to arms performing well, and decreases allocation to arms performing poorly. In multiple arm trials, this has advantages over fixed randomization.

I’d be inclined to think hospitalizations are more accurate than case counts. People are more likely to take a really sick kid to a doctor and get counted while mild infections go unreported. Of course hospitalizations are fewer and more variable. Also….

Interesting experimental idea. Curious if the result indicates a prior distribution on “coins are fair” as much as a statement on likelihoods. Would have been interesting to also investigate a “novel” source of randomness.

As best I can tell they can grab me or my kids off the street, move us around fast enough we don’t know where to file a claim, intimidate our potential lawyers to not represent us, and then once we are outside the US claim “oops nothing anyone can do”. How is anyone ok with this?

I believe virtually all trial results should be public. Sponsors pay for trials but participants give precious resources. Society benefits from full transparency. Deidentified of course, likely with delays, but if you experimented on a human you owe humanity the results.

I see no route to randomize. Who would enroll on either side of the vaccine “debate”? So it’s either observational and prospective (which provides cover to say “we don’t have an answer yet”) or retrospective in which case hard to see value added (can see value subtracted…) Happy to be proven wrong.

With 331 estimates (really any modest number) the highest estimates tend to be biased high and the lowest are biased low. Whatever the truth is, the estimates tend to be more spread out than the truth. A Bayesian hierarchical model would be tailor made for this.

Seeing proposals that FDA should approve drugs based only on a proof of safety, not efficacy. I’m not sure this is even a thing. There is no short, small trial that shows a drug is safe, and even if there were, a “safety only” policy comes with other problems….a thread. @elizabethjacobs.bsky.social
