Causality, menopause, and depression: a critical review of the literature

Three errors occurred in figure 1 of this paper by Louise Nicol-Smith (16 November, pp 1229–32). The perimenopausal area that is crosshatched in Avis et al9 1993 should have been plain while that in Avis et al8 1994 should have been crosshatched. The dotted box in the age column that straddles Hunter25 1986 and Ballinger et al26 1985 should have been with Holte17 1992. The note on sample size in the legend is wrong owing to an editorial error. It should have read: “Note: Sample size generally was the number available for the relevant data analysis. However, in the cases of Hallstrom and Samuelsson33 1985, Koster and Davidsen6 1993, and Matthews et al14 15 1994 and 1995 the number stated is the sample size at study outset.”
