Trends of different drug-resistance patterns among 1484 culture-confirmed TB cases in Hainan, 2014 to 2019. In new cases, for INH resistance (χ2 = 2.813, P = 0.729); for RIF resistance (χ2 = 3.181, P = 0.672); for MDR-TB (χ2 = 4.210, P = 0.520); for XDR-TB (χ2 = 4.383, P = 0.496). In retreatment cases, for INH resistance (χ2 = 9.512, P = 0.090); for RIF resistance (χ2 = 14.257, P = 0.014); for MDR-TB (χ2 = 10.328, P = 0.066); for XDR-TB (χ2 = 7.670, P = 0.175). Note: *new cases, **retreatment cases. Abbreviation: INH-R, isoniazid resistance; RIF-R, rifampin resistance; MDR-TB, multidrug resistant tuberculosis; XDR-TB, extensively drug resistant tuberculosis
