Correlation between phenotypic resistant level and mutations conferring INH resistance. Low-level resistance: 0.5 ≤ MIC ≤2 mg/L; moderate-level resistance: 4 ≤ MIC ≤16 mg/L; high-level resistance: MIC ≥32 mg/L; asterisk represents significant differences [P value is less than the false discovery rate (FDR) 0.017] between the group with various mutation types and the group without mutations
