• The regression coefficient β (with 95% CI) denotes the mean change in the risk factor per 2 days which is associated with a 1000 steps/h higher walking speed. For example, a 1000 steps/h higher walking speed is associated with an increase in HDL cholesterol of 0.01 (95% CI 0.00 to 0.02) mmol/l (model III) per 2 days, translating to 0.06 (95% CI 0.00 to 0.12) mmol/l during the whole 12-day walking tour. Model I = crude, model II = age and gender and model III = age, gender, current smoking, BMI and heart rate at baseline.
