Extended Data Fig. 4: Power analysis.
From: No statistical evidence for an effect of CCR5-∆32 on lifespan in the UK Biobank cohort

Power to detect effects on mortality of a genotype with the frequency of ∆32/∆32 in a sample of the same total size and mortality rate as the cohort studied here, as a function of relative risk. The power to detect a 20% increase in mortality rate at a 0.05 significance level is 75%.
