This is the partial deposition of Hal Morgenstern, Ph.D. In it, he discusses the relative risks of developing tardive dyskinesia after using Reglan or Metoclopramide.
Q. Would you calculate that for me on this piece of paper?
A. I remember that I had to solve for something in this, let's see, okay. There
were 51 metoclopramide and 51 others. Okay. I took -- multiply that times that
divided by that times that.
Q. Would you write that down for me? So your odds ratio is the product of 15 times
42 divided by the product of 36 times 9?
A. As I recall.
Q. And you say o-r with a --
A. Little hat above it.
Q. Thank you. I thought there was a technical term for it.
A. There probably is. Most people just say hat. It means estimate. I'm just used
to doing it.
Q. And why do you say this is an odds ratio estimate?
A. Because I estimated it from the data.
Q. And what I'm getting at is, do you ever calculate odds ratios that are not
estimates?
A. Not from data.
Q. And this gave you 1.94, correct?
A. Uh-huh.
Q. And the confidence interval was .76 to 4.97?
A. Yes, if you're reading from my -- yes.
Q. And that confidence interval includes one, correct?
A. Yes.
Q. And what is the significance of the fact that the confidence interval includes
one?
A. Just means that the 95 percent confidence interval includes the null value.
Q. You chose a 95 percent confidence interval; why?
A. Just standard, I could have chosen anything, most common, some people use 99,
some people use 90.
Q. But 95 percent is the most standard confidence interval used in epidemiology?
MR. PITTLE: Object to the form.
A. I think so.
Q. Now look at the paper on page 1472. Under tardive dyskinesia, it says 29
percent (n=15) of --
A. I'm sorry, where are you?
Q. 29 percent (n=15) of metoclopramide users met the case definition of tardive
dyskinesia compared with 17.6 percent (n=9) of non-users, correct?
