Fig. 2

Proportion of incident TB cases with MDR among all cases based on city level. a Proportion of incident TB cases with MDR obtained from articles reports, the white blank areas refer to no data available. b Kriging interpolation result. We did the Kriging interpolation analysis only in eastern and central area (right side of red line in Fig. 2a) since fewer data was available in western areas. c Estimate the proportion of incident TB cases with MDR in nationwide. We used the provincial date in Fig. 3 to make up the west blank area to estimate the proportion of incident TB cases with MDR in nationwide. Therefore, the proportion of incident TB cases with MDR of western region in Fig. 2c was the provincial data from Fig. 3a, and the proportion of incident TB cases with MDR of eastern and central area in Fig. 2c was the Kriging interpolation result from Fig. 2b
