BACKGROUND: All-cause mortality, based on national tuberculosis programme (NTP) register deaths, may under- or overestimate tuberculosis (TB) specific mortality in the population. OBJECTIVE: To assess the factors influencing this measurement in a single large population with high TB prevalence and mortality.
