Risk factor measurements unavailable for 29-40 of the 502 subjects (6%-8%), except for distance walked which was unavailable for 92 subjects (18%). †Body mass index also adjusted for baseline measurement. ‡Smokers at baseline who were confirmed non-smokers at 1 year (serum cotinine concentration ⩽78 nmol/l (⩽13.7 ng/ml)). Subjects who were not assessed were assumed to be smokers.
