Conceptual Framework, with study definitions and an example of a realized diagnostic pathway. Diagnostic delay comprises patient and health system delays. Patient delay can be divided into two components: care-seeking and community contact delays. Within the community, a patient may contact several individuals, with each visit contributing time to delays (see text). In the example of a realized diagnostic pathway, the time contributed by social contacts is equal to the sum of the days between the social contact and the first TB provider, while the time contributed by non-TB providers was calculated as the number of days from non-TB provider 1 to the social contact. The time contributed by non-TB provider 2 is not counted toward contributions to community contact delay, as this visit took place during the health system delay period and so is counted toward health system delay
