*Values are no. (%) cases except as indicated. OR, odds ratio; SNP, single-nucleotide polymorphism; TB, tuberculosis. †ORs for the history of incarceration comparing those in large clusters with those unclustered or in small clusters. ‡ORs adjusted for age, ethnicity, sex, and history of TB treatment.
