*Using the average MDR-TB rate among 2009–2013 to calculate the estimated MDR-TB cases under 100% screening situation. Group 1: New cases persisting sputum culture or smear positive at the end of the 2nd month after treatment; Group 2: New cases of initial treatment failure; Group 3: Re-treatment cases of treatment failure; Group 4: Cases with poor treatment compliance: Patients receiving treatment and interruption and re-treatment again; Group 5: Recurrence cases. Estimated MDR-TB number = TB cases × average MDR-TB rate. MDR: Multidrug resistant; TB: Tuberculosis.
