Association of leisure-time physical activity (any versus none) with all-cause mortality, non-vascular death, and vascular death in the Northern Manhattan Study based on body-mass index.

		All-cause mortality: ‡ Adjusted Hazard ratio and 95% confidence interval	Non-vascular death: Adjusted Hazard ratio and 95% confidence interval	Vascular death: ‡ Adjusted Hazard ratio and 95% confidence interval
Body-mass index less than 30	Any leisure-time physical activity versus none *	0.77 (0.68-0.88)	0.76 (0.64-0.91)	0.80 (0.65-0.97)
	Third quartile of MET-score versus no activity *	0.81 (0.71-0.93)	0.79 (0.65-0.96)	0.82 (0.66-1.04)
	Fourth quartile of MET-score versus no activity *	0.70 (0.59-0.83)	0.73 (0.59-0.90)	0.75 (0.59-0.97)
Body-mass index greater than or equal to 30	Any leisure-time physical activity versus none *	1.07 (0.86-1.34)	0.93 (0.68-1.28)	1.27 (0.91-1.79)
	Third quartile of MET-score versus no activity *	1.08 (0.84-1.38)	0.98 (0.69-1.39)	1.19 (0.81-1.74)
	Fourth quartile of MET-score versus no activity *	1.06 (0.79-1.43)	0.84 (0.54-1.31)	1.43 (0.93-2.20)
