Description of Collaborative Activity: |
The Long-term Oxygen Treatment Trial is a randomized controlled clinical trial to assess the efficacy of around-the-clock, supplemental oxygen therapy in subjects with chronic obstructive pulmonary disease and moderately severe hypoxemia. NHLBI will administer and oversee the study, and Medicare will cover the costs of items and medical services that are generally available through that program to beneficiaries enrolled in the trial. |
