Warren R. Muir, Fh.D. Executive Office of the President Council on Environmental Quality 722 Jackson Place N.w. Washington, D.C. 20006
Dear Dr, Muir:
Due to the press of time, I am sending the tables you requested from Dr. Johnson directly to you, with copies to him.
We were unable to provide the person-years data because our program is such that we would have had to run it once for each cell in the table. It could be done, but not in the availabl time. The distribution of Table 9 can be used to get a rough estimate of person-years of observation for those not found, up to the date when they terminated, by assuming that date of hire and date of termination are uniformly distributed over time.
You will notice that we changed the time interval 0-4 to 1-4, since every worker in our study had at least one year in an exposed job.
I hope this arrives in time to be of use to you.
Yours sincerely.
William R. Gaffey, Ph.D. Director of Health and Epidemiological Studies
