A few errors inadvertently slipped through in this paper by P A Logan and colleagues (11 December, pp 1372-4). In the full ( version, in three instances the confidence limits became transposed: in figures 2 and 3 the confidence intervals for the patient's general health questionnaire should have been -3.77 to 1.02 and -3.54 to -1.14 respectively, and in figure 3 the interval for the carer's general health questionnaire should have been -3.28 to 2.41. Errors also occurred in table 2 (full and abridged versions of the paper): the number (proportion) of controls who got out of the house as much as they wanted should have been 31 (38%) at four months and 29 (35%) at 10 months; the numbers needed to treat at these two stages were 3.7 and 3.8 respectively.
