These HIV-related interventions were associated with significant declines in TB CNRs: between the highest CNR prior to national roll-out of ART (in 2004) to the lowest recorded CNR after national IPT roll-out from 2012, these were (1) for all TB case (510 to 173 cases\/100 000 population; 66% decline, p&lt;0.001); (2) for those with new TB (501 to 159 cases\/100 000 population; 68% decline, p&lt;0.001) and (3) for those with new clinically diagnosed PTB (284 to 63 cases\/100 000 population; 77.8% decline, p&lt;0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study shows the population-level impact of the continued scale-up of ART among PLHIV and the national roll-out of IPT among those in ART care in reducing TB, particularly clinically diagnosed TB which is largely associated with HIV.
