Macrolide Resistance of Mycoplasma pneumoniae in four regions. (A) The pie chart shows the proportion of macrolide resistance across two categories: A2063G (blue) and WT (orange). Each slice represents the percentage of variants among a total of 421 samples. The difference in distribution between wild-type and variants was assessed using a Chi-square test (****: p < 0.0001). (B) The absolute number of WT and variant individuals from four regions in China—Zhejiang (southeast), Liaoning (northeast), Guizhou (southwest), and Hubei (central).
