Smear-positive	1,527 (33)	3,072 (67)	Referent
Smear-negative	756 (27)	2,026 (73)	0.82 (0.75–0.90)

^*Excluding patients reported after 2006 (536 smear-positive, 431 smear-negative), not documented as alive at diagnosis (191 smear-positive, 362 smear-negative), with no documented treatment (35 smear-positive, 112 smear-negative), or whose recorded outcome date preceded start of therapy or was missing (153 smear-positive, 110 smear-negative).

^†Other outcomes not represented as a column in this table include patients who moved during treatment or were lost (650 smear-positive, 484 smear-negative), were uncooperative with therapy (52 smear-positive, 45 smear-negative), or whose outcomes were otherwise not known (35 smear-positive, 30 smear-negative),

^§Adjusted for gender, age group, race/ethnicity, nationality, incarceration, alcohol and drug use, and previous TB; after adjustment, homelessness in the previous year was the only examined covariate that was no longer statistically significant.
