Flow diagram illustrating the process of linking databases and selecting individuals for survival analysis. The 2013 National Census of Penitentiary Centers (green) was matched with the National Registry of TB Cases of the NTP, period 2010–2021 (blue). This analysis revealed 1096 cases of TB. PDL from prisons without documented records of entry and exit dates were subsequently excluded (yellow). These cases represent a total of 2996 PDL in five prisons. Out of these, 451 have developed TB and 2545 prisoners did not develop TB. PDL that had a prolonged duration of incarceration were excluded (orange).
