Figure 1 Trends for the quantity and proportions of different subgroups among the total elderly primary DR-TB cases, Shandong, China, 2004–2019*. (A) Trends for MR-TB, MDR-TB, PDR-TB among the elderly with primary TB; (B) Trends for the elderly primary DR-TB cases of different sex (male or female); (C) Trends for primary DR-TB cases with or without cavity; (D) Trends for primary DR-TB cases with or without smoking history; (E) Trends for primary DR-TB cases with or without drinking history; The proportions of each subgroups were calculated as follows: (the quantity of each subgroups/the quantity of the total elderly primary DR-TB subgroups in the same year) × 100%; The χ2 and linear regression results are shown in .
