Table 3. Baseline resistance patterns among individuals with DST results (n = 1020).

Characteristic NRA DST (n = 590) n (%) Conventional DST (n = 430) n (%) P value
INH- and RMP-susceptible 316 (53.6) 224 (52.1) 0.14
INH- or RMP-resistant 84 (14.2) 47 (10.9)
MDR-TB 190 (32.2) 159 (37.0)

DST = drug susceptibility testing; NRA = nitrate reductase assay; INH = isoniazid; RMP = rifampin; MDR-TB = multidrug-resistant tuberculosis.
