The Ghost of Christmas Past: health effects of poverty in London in 1896 and 1991

The penultimate paragraph of the Results section in this paper by Dorling et al (23-30 December, pp 1547-51) should read: "The results of further correlation analyses suggest that for deaths under the age of 65 the modern index makes a slightly greater contribution to predicting all cause mortality in 1991-5 (r = 0.56, P [is less than] 0.001) than does the Booth index (r= 0.46, P [is less than] 0.001). This is substantiated by the results of the partial correlation analyses, where r= 0.39 (P [is less than] 0.001) when mortality is correlated with the modern [not the Booth] index, controlling for the Booth [not the modern] index, but r = 0.08 (P = 0.36) when mortality is correlated with the Booth index, controlling for the modern index."
