From: Evaluation of exposure-specific risks from two independent samples: A simulation study

Parameter

Possible values

Exposure probability

.05, .20

Probability of disease among unexposed

.02, .09

RR

1.0, 1.5, 2.0, 2.5, 3.0, 4.0, 5.0

Sample size combinations for the overall risk and RR (N1/N2)

250/250*, 1,000/1,000, 1,000/5,000, 5,000/1,000, 5,000/5,000

  1. *Note: The 250/250 sample size combination was only performed in Scenario 4 (probability of exposure = .20; probability of disease among unexposed = .09).
