Participants (technique, sample characteristics)	Primary exploratory outcomes	Justification of choice of method and participants
Uninvestigated chronic coughers (IDIs; n=20; F=8; M=12; age range 18–77; average age=36; balanced by marital status)	Experiences of symptoms; steps taken and reasons; reasons for not being investigated	The stigma of TB/cough/HIV, and personal data require private interview setting; IDIs target information about individual experience.

Health workers (FGDs; n=2; both mixed sex; no. of participants=20)	Views on 1) men's care-seeking, 2) interface of health services with community	As for community FGD above; Also, participants were expert informants based on their special knowledge.
Health stakeholders (participatory workshop; 27 participants; F=14; M=13)	Develop candidate interventions; discuss acceptability of proposed interventions	Participants were experts in different domains related to health [see (39)]
