Blood Cd concentrations in COPD patients with different disease progressions. Blood Cd concentration was detected using ICP-MS. The levels of blood Cd concentration were compared in COPD patients with different progressions. A Blood Cd concentrations in COPD patients with different acute exacerbations. B Blood Cd concentrations in COPD patients with different hospitalizations. C Blood Cd concentrations in COPD patients with different hospital stays. D Blood Cd concentrations in dead and survived COPD patients. *P < 0.05, **P < 0.01
