Name | Definition |

Indigenous peoples | Those who self-identified as belonging to this population group defined previously in literature [16, 23, 24] |
Low incidence countries | Countries with TB incidence less than 15 cases per 100,000 population |
Medium and/or high incidence countries | Countries with TB incidence of at least 15 cases per 100,000 population |
Diagnosis delay (DD) /Time to diagnosis (TDx) | The duration between the onset of symptoms and diagnosis, the latter defined as a positive acid-fast bacilli (AFB) smear and/or nucleic acid amplification test, positive culture of a Mycobacterium tuberculosis complex organism or clinical diagnosis |
Total delay (TD) /Time to treatment (TTm) | Duration between the onset of symptoms and treatment, which is commonly stratified into two main parts, patient delay and health system delay |
Health System Diagnostic delay (DCD) | Duration between the first visit with a medical professional to diagnosis as defined above |
Health System Treatment delay (TmD) | Duration between diagnosis (as defined above) and treatment |
Patient delay (PD) | The time from onset of symptoms to first visit with a medical professional |
Health system delay (HD) | The time from the first visit with a medical professional to start of treatment |
Cut-off threshold | Either defined as a median estimate or arbitrarily chosen within a study to differentiate between a delayed or timely event |
Delayed event | Any duration greater than the cut-off threshold |
Timely event | Any duration less than or equal to the cut-off threshold |
