  1. aMissing data were handled using multiple imputation. Study baseline is T1 (1995–1999), Initial cohort (MCCS) recruitment is T0 (1990–1994). bMDS groups: low (scores 0–3), medium (4–5) and high (6–9); cPhysical activity groups: low (e.g. walking twice a week or less), medium (e.g. jogging twice a week), high (e.g. running three or more times a week)
