[Correspondence] Management of primary spontaneous pneumothorax: less is more – Authors' reply

We thank Simon Brown and colleagues for their comments regarding our study.1 We agree that generally less is more in terms of management of primary spontaneous pneumothorax and that, together, our two randomised studies provide important data that should be incorporated into future guidelines.1,2 However, we feel that the studies might reflect two differing populations of patients with primary spontaneous pneumothorax. The median scores for pain and breathlessness at enrolment in Brown and colleagues' study2 were lower (interventional group: pain 2/10 and breathlessness 1/10; conservative group: pain 2/10 and breathlessness 1/10) than in our study1 (ambulatory group: pain 41/100 and breathlessness 43/100; standard care group: pain 37/100 and breathlessness 41/100).
