The paper discusses the problem of interval estimation for the relative risk when some test‐retest data are available on random subsamples drawn from case‐control studies. It is shown that, although the upper portion of the interval may be very wide indeed, the lower bound of the interval estimate may be improved considerably by the collection of even modest amounts of repeat measurements.
