GMR: geometric mean ratio, LTBI: latent tuberculosis infection, APTB: active pulmonary tuberculosis, SES: socioeconomic status.
h 23 uninfected controls, 24 LTBI and 34 APTB cases.
i Results were generated using linear regression and the factors were adjusted for one another.
j Q values were computed for multiple comparisons between M.tb infection states and uninfected controls using the Bonferroni method.
¢ LTBI is baseline comparison group.
Crude GMRs can be found in S3 Table in the supporting information.
