Pulmonary artery catheters

An incomplete reference in this editorial by Simon Finfer and Anthony Delaney (BMJ 2006;333:930-1, doi: 10.1136/bmj.39017.459907.BE, 4 Nov) might have caused readers difficulty in searching for the cited report. Reference 3 (Health Technol Assess 2006;10:1-150) should have included the issue number (29). The link on bmj.com was also wrong but has now been corrected.
