Effect of insulating existing houses on health inequality: cluster randomised study in the community

An editorial error in table 6 of the full version (on bmj.com) of this research paper by Philippa Howden-Chapman and colleagues might have confused readers (BMJ 2007;334:460 doi: 10.1136/bmj.39070.573032.80). For the control group in the “After intervention” column, under the subheading “Days off work” the entry should read 19 (577), not 19 (/577).
