Estimated crude median national polymyxin(s) resistance proportions for a E. coli and b Klebsiella spp. for studies including samples from 2010 and later. For those nations with ≥ 100 isolates from qualifying studies (see Methods), median proportions across studies were calculated. Where < 100 isolates, data were deemed insufficient to estimate proportions and resistance is represented as either detected or not
