Key Points

  • This research aims to establish sample size requirements for intervention trials where clusters are the unit of randomization.
  • Analyzed cases involving the comparison of two means and two proportions.
  • Discussed necessary modifications to standard statistical analyses.
  • Provided guidelines for calculating sample sizes in cluster randomized settings.
  • Outlined specific sample size requirements for both comparison types.
  • Identified critical statistical adjustments necessary for valid analysis.
  • Demonstrated variations in sample size calculations depending on the unit of randomization.

Abstract

Sample size requirements are given for intervention trials in which the unit of randomization is the cluster. Cases dealt with include the comparison of two means and the comparison of two proportions. Required modifications to the standard statistical analyses are also discussed.
