Table 2 The probability* (y) of the LQAS test failing to reject the null hypothesis H0: p ≥ 10% for different levels of the true population prevalence (x).

From: Interpreting results of cluster surveys in emergency settings: is the LQAS test the best option?

True population prevalence of GAM 5% 6% 7% 8% 9%
Probability of failing to reject H0: p ≥ 10% 12.3% 30.2% 52.4% 72.2% 86.0%
  1. * Based on binomial test
  2. Assuming survey sample size of 198 and decision rule (count of GAM cases to reject null) of 13 (n = 198, d = 13).
