The Cough Audio triaGE for TB (CAGE-TB) project aims at promoting the adoption of mobile health-based cough audio triage testing for active pulmonary tuberculosis in health facilities in high-burden settings. Specifically, the study aims are;

a) To generate and separately validate a cough audio classifier that meets the criteria for the World Health Organization (WHO) triage test target product profile for sensitivity and specificity,

b) To produce data on potential cost savings, and

c) To package the underlying technology into an easy-to-use smartphone app built using human-centered design ready-for-use in large-scale clinical evaluations.
