"WebThe baseline incidence rate is related to the effect size. If it is hypothesized that a rate has increased or decreased, the baseline rate and the effect size must both be known to calculate the power for detecting such a change. With knowledge of the above factors, the power of a statistical test can be calculated for a given sample size. " - Incidence density calculation
