The authors of this Research paper (BMJ 2009;339:b4904, doi:10.1136/bmj.b4904) have alerted us to an error in table 1. Under the column heading “England and Wales (%)” the percentage for “white” should have been 98.5% [not 89.2%], and the percentage for “non-white” should have been 1.5% [not 10.8%]. This correction necessitates further corrections to the paper.
Under the section “Representativeness of study sample” the second sentence in the second paragraph should read: “Sociodemographically, the 85 year olds living in Newcastle upon Tyne and North Tyneside are generally comparable to those in England and Wales.” The fourth sentence in the second paragraph of the section “Strengths and limitations of the study” also needs to be corrected. This sentence should read: “Comparison of the Newcastle 85+ cohort with sociodemographic data from the national census 2001 showed our sample to be broadly representative of England and Wales.”
