Is conservative treatment for primary spontaneous pneumothorax noninferior to interventional treatment?

BEEM Bottom Line

Why is this study important?

Most cases of PSP resolve spontaneously with reduced healthcare costs and patient discomfort. This trial assesses whether conservative treatment of moderate to large PSP is noninferior to interventional treatment.
