All-cause mortality	0 MET-hours/week: RR = 1 (m, f); 0.1 < 7.5 MET-hours/week: RR = 0.82 (m), RR = 0.77 (f); 7.5 < 15 MET-hours/week: RR = 0.71 (m), 0.67 (f); 15 < 22.5 MET-hours/week: RR = 0.63 (m), RR = 0.64 (f); 22.5 < 40 MET-hours/week: RR 0.61 (m), RR = 0.60 (f); [53] ²	1.00 (m, f)	0.70 (m), 0.68 (f)	0.61 (m), 0.64 (f)

IHD Ischemic heart disease; MET Metabolic equivalent of task; m Males; f Females; RR Relative risks.
¹ All of the studies underlying the meta-analysis are adjusted for multiple potential confounding variables, but not all confounders were adjusted for in every study; the estimate from meta-analysis was unadjusted for BMI
² Adjusted for smoking, alcohol, education, marital status, history of cancer, history of heart disease and BMI
