Effect of sensitivity on the Type I error of a cluster survey involving 20 villages, and 50 people/participant.
A specificity of 99.8% was assumed. The critical cutoff was ≥ 2 positive tests in at least 1 village. The calculations were made for a true prevalence of 2%. At least 60% sensitivity is required to reach a Type I error of < 5%.
