Data extraction
Independent data extraction was performed by two authors (AA, ZWB), and
the inconsistencies were resolved by the third author (GD). The
extracted data includes; study characteristics (author, publication
year, study area per regional state, study setting, data collection
period), study age-group, the type of drug-resistant-TB (any
drug-resistant TB, RR-TB, MDR-TB), the sample size (cases, controls),
and different risk factors of DR-TB using the odds ratio along with the
95% CI. We summarized the extracted data using Microsoft Excel 2016
