Categorizing patients according to home situation and cardiopulmonary outcomes. Elevated TRV (A), reduced 6MW distance (B), reduced oxygen saturation (C), and CPD (D) at baseline in PUSH and elevated TRV (E), reduced 6MW distance (F), reduced oxygen saturation (G), and decline in cardiopulmonary function (H) at follow-up compared with baseline in PUSH. In each category, the observed numbers of patients were presented. In all panels, the proportions of outcome per home situation are presented above each bar.
