A bacteriologic relapse was defined as a patient who became consistently culture-positive [defined as at least 1 of the following]: a at least 1 sputum mycobacterial culture growing at least 10 colonies of MTB on solid medium; b 2 or more respiratory secretion cultures that are positive for MTB in liquid media; or c any culture from an extrapulmonary site that is positive for MTB during follow-up after successful completion of initial anti-TB treatment.
Patients who defaulted before completing study treatment and returned later with culture-positive tuberculosis were termed failures after non-adherence.
