Title: Sample size requirements for interval estimation of the odds ratio.

Authors: Satten, G A; Kupper, L L

Published In Am J Epidemiol, (1990 Jan)

Abstract: Sample sizes are calculated for unmatched case-control (or cohort) studies where the goal is interval estimation of the odds ratio. The procedure used gives the smallest sample size for which a 100(1-alpha)% confidence interval for the log odds ratio will not exceed a specified width with specified probability (1-gamma). Tables of sample sizes for various choices of parameter values are presented. Considerable disagreement is found with a published method which has as its basis expected cell counts.
