* Countries that reported at least one MDR-TB case in 2013.
† Estimates of the proportion of new and previously treated TB cases that have MDR-TB were produced using modelling (including multiple imputation) that was based on data from countries that were considered to be similar in terms of TB epidemiology for which data do exist.
