Effect of withdrawal of co-proxamol on prescribing and deaths from drug poisoning in England and Wales: time series analysis

The authors of this research paper, Keith Hawton and colleagues (BMJ 2009;338:b2270, doi:10.1136/bmj.b2270), have advised us that the data used in their study have since been revised by the Office for National Statistics because of problems identified in the coding of deaths involving analgesic compounds. The altered results do not affect the general findings or overall conclusions. For further detail, see the first author’s Rapid Response (www.bmj.com/content/338/bmj.b2270.full/reply# bmj_el_255838) or email him (keith.hawton@psych.ox.ac.uk).
