Temporal Trends of In-Hospital Mortality
(A) The temporal trends of crude and age-adjusted in-hospital mortality (A-1, all; A-2, male; A-3, female). The crude in-hospital mortality showed decreasing trends in the overall, male, and female (all; P < 0.001). The age-adjusted in-hospital mortality also showed decreasing trends in the overall (black), male (blue), and female (red) (all; P < 0.001). (B) The temporal trends of age-specific in-hospital mortality in all (B-1), male (B-2), and female (B-3). (C) The temporal trends of in-hospital mortality classified by Killip class in all (C-1), male (C-2), and female (C-3).
