Fig. 3

Drug resistant status of Haemophilus influenzae. (a) Trends of different H. influenzae drug resistant status from 2007 to 2018 are shown. (b) β-lactamase-positive rates in MDR, non-MDR, XDR, and non-XDR H. influenzae isolates are shown. The number of each group is shown in the bar. P-values are obtained from Pearson Chi-square tests. Proportions of different drug resistant status under (c) different specimen types and (d) different specimen sources are shown. Pearson Chi-square tests were used to assess the significance of each analysis. MDR, multiple drug-resistance; NR, no resistance; SDR, single drug-resistance; TDR, two drug-resistance; x̄, mean value; XDR, extensive drug-resistance
