Cards on the Table
Starting over When I started in the pharmaceutical industry almost 40 years ago, I knew nothing about clinical trials. I was puzzled by a strange ritual that seemed to be generally observed.

So you carried out a controlled clinical trial? Bravo. Make sure you carry out a controlled analysis. You can bin those within-group standard errors, comparisons back to baselines and dynamite detonator plots for a start.

It used to be that only at most three or maybe four people read a PhD. The author, the supervisor, the examiner(s). Nowadays even the “author” might not have read it.

At any celebration, the role of a statistician, especially a frequentist one, is often that of a bad fairy. Nobody invited them, they turn up at the end, spread gloom and send everyone to sleep. My comment on the recent FDA guidance n Bayesian methods.

Research in psychology. 1) You use your students as subjects & generalise your results to all mankind 2) You assume your students are as variable as mankind at large 3) Because if they weren’t that would make the SMD a stupid measure 4) & everyone knows it’s the way you should report results.

Fascinating stuff. However, IMO, the value of double blind trials is not just dealing with patient- centred biases but physician-biases and this is often overlooked.
