Relative contributions of risk factors to risk of AMI in the INTERHEART study^a,¹⁶⁶

Risk factor	Odds ratio	Population attributable risk
Smoking	2.87 (for current vs never)	35.7% (for current and former vs never)
Raised ApoB/ApoA1 ratio	3.25 (for top vs lowest quintile)	49.2% (for top 4 quintiles vs lowest quintile)
History of hypertension	1.91	17.9%
Diabetes	2.37	9.9%
Abdominal obesity	1.12 (for top vs lowest tertile) 1.62 (for middle vs lowest tertile)	20.1% (for top 2 tertiles vs lowest tertile)
Psychosocial factors	2.67	32.5%
Daily consumption of fruits and vegetables	0.70	13.7% (for lack of daily consumption)
Regular alcohol consumption	0.91	6.7%
Regular physical activity	0.86	12.2%

^aAll risk factors were significantly related to AMI (P < 0.0001 for all risk factors and P = 0.03 for alcohol).
