*Because of the monthslong duration of TB treatment, outcome data can require up to 2 years after the initial case report; therefore, patients with incident TB disease in 2016 and 2017 were excluded from this table. Had we included them, the proportions of patients who died before TB treatment could be started were similar: 375 (2.8%) among the 13 281 adult patients with TB with diagnosed diabetes and 1303 (2.2%) among the 58 574 with unknown diabetes status during 2010–2017.
†Denominators for these proportions are based on the 1052 adult patients with TB with diagnosed diabetes and the 2610 with unknown diabetes status who began TB treatment but died before achieving treatment completion.
‡Denominators for these proportions are based on the 8408 adults with diagnosed diabetes and the 41 471 adults with unknown diabetes status who began TB treatment and did not die during treatment.
