The trial data comprise questionnaire information obtained at baseline and at 1-year follow-up. The data are as collected, though for analysis purposes some categorical variables have been made numeric. Thus categories that offered ranges have been replaced with the mid-point of the category. For example, 2-4 has been replaced with the numerical value of 3. A few variables have been removed from the original dataset, such as date of birth, to preserve confidentiality. Three versions of the dataset are available: an SPSS portable file (.por); a Stata data file (.dta); and an SPSS data file (.sav).
