Trend of mortality rates reported during and after TB treatment stratified by comorbidity status among persons who initiated treatment for RR or M/XDR TB in the country of Georgia from 2009 to 2017. Mortality rates during and post-TB treatment were estimated by 6-month period by building independent life tables. Mortality rates during and post-TB treatment were expressed per 1000 populations. Mortality rates were then plotted continuously with a single interruption point to mark the end of TB treatment (red dashed line). The beginning of survival time of ‘TB treatment phase’ (T_0-treatment) marks the TB treatment initiation date. Thus, the point at T₆ in the ‘TB treatment’ phase indicates the mortality rate at 6-month after TB treatment initiation. The beginning of survival time of ‘Post-TB treatment’ phase (T_{0-post-TB treatment}) marks the end of TB treatment (i.e., could be treatment completion or lost to follow-up dates). Thus, the point at T₆ in the ‘Post-TB treatment’ phase indicates the mortality rate at 6-month after TB treatment ended.
