  1. WT: no macrolide resistance mutation detected (group A); mutant M. pneumoniae: A2063G or A2064G mutation detected (group B); low frequency: macrolide resistance mutation present at low percentage (≧S and < 50%) (group C); high frequency: macrolide resistance mutation present at high percentage (≧50%) (group D); two groups: WT (group A) and mutant M. pneumoniae (group B); three groups: WT (group A), low frequency (group C) and high frequency (group D)
