*Percentages indicate falling in each group within a cluster. LLR: log likelihood ratio; Ob, number of observations in a cluster; RR, relative risk, computed as the ratio of the proportions of the number of Buruli ulcer cases in each category out of the total number of cases inside the cluster versus outside.
