![Associations of environmental and clinical risk factors with genetic relatedness based on pair-level data using hierarchical Bayesian regression models in phylogeographic analysis of Mycobacterium kansasii isolates from patients with M. kansasii lung disease in industrialized city, Taiwan. A) Odds ratios for pairs of M. kansasii isolates to be in a genetic cluster (using the single-nucleotide polymorphism [SNP] cutoff of 45). An odds ratio of >1 suggests that the risk factor was associated with genetic clustering. B) Risk ratios for increase in SNP distance between pairs of isolates. A risk ratio of <1 suggests that the risk factor was associated with a shorter pairwise SNP distance. The 3 smaller water purification plants (Lingkou, Baolai, and Lujhu) were not considered in the analysis as they together only provided service to 6 participants.](/eid/images/24-0021-F2.jpg)
