title: Sample size calculations for rescreening cytologic smears.
abstract: OBJECTIVE
  To describe a method of calculating sample size if rescreening of cytologic material becomes necessary for legal or other reasons. The number of specimens to be reexamined must be large enough to provide adequate confidence in the results and small enough to minimize the cost of investigation.
  
  
  CONCLUSIONS
  Except under very unusual conditions, the sample size is larger than generally thought.
