Fig. 3

Geographical distribution and prevalence of drug-resistant M. tuberculosis complex isolates in WANETAM study sites. The proportions of resistant strains within the total bacterial population per country are mapped (for Nigeria the average of the two study sites, Lagos and Ibadan, is displayed). The maps are stratified by new (left column) and retreatment patients (right column). The upper panel shows geographical distribution of the proportion of isolates with any first-line drug resistance. The centre panel shows the proportion of MDR amongst the total bacterial population. The lower panel shows the proportional geographical distribution of pre-XDR within the total population of MDR isolates. The sample sizes for each country are as follows (country name [n = new patients/n = retreatment patients]): Burkina Faso [20/1], The Gambia [9/95], Ghana [15/112], Guinea-Bissau [32/4], Mali [150/58], Nigeria [41/132] (Lagos and Ibadan combined), Senegal [55/20], Togo [94/112] (for further details see Tables 3 and 4)
