### Socio-Demographic Characteristics  
Of the total of 3884 patients with TB-DS, 3858 (99.33%) were classified in the following social risk categories: 3858 (99.33%) rural people, 10 (0.25%) people suffering from drug dependence (DD), and 16 (0.41%) homeless people (H). Seventy-five percent of the TB-DS patients are male, most of them in the age category 45-54 years, with ISCED 2 (International Standard Classification of Education) education level, i.e., secondary school. More than half of the selected patients did not have a job at the date of entry into the project; only 19% are employed, and the difference in these two categories is people living on social assistance, pensions, or disability benefits (Table 1). \begin{table}

Table 1: Structure of TB-DS patients analyzed according to socio-demographic characteristics and level of education by vulnerable groups (VGs). Of the 217 DR-TB patients, 199 (91.71%) were rural people (RP), 12 (5.53%) were people suffering from drug dependence (DD), and 6 (2.76%) were homeless (H). The proportion of males is also preserved in the DR-TB group, with 77% males exhibiting similar characteristics to the DS-TB group in terms of age and level of education. However, it should be mentioned that in the subgroup of injecting drug users with TB, 50% are unemployed, 25% are retired, and 16% are employed (Table 2). \begin{table}
