From: New epidemic cluster of pre-extensively drug resistant isolates of Mycobacterium tuberculosis Ural family emerging in Eastern Europe

  Clade C Clade B Clade A
Clade C P < 0.01 P < 0.01
Clade B W = 0 P < 0.05
Clade A W = 209 W = 987
  1. Upper right triangle – probability of rejecting null hypothesis about lack of significant difference between mean mutation rates (amino acid substitutions) in three Clades. Lower left triangle shows Wilcoxon-Mann-Whitney statistics values. Lognormal relaxed clock model was used for calculations
