| RR | 95% CI | p Value | |
| Univariate analysis | |||
| Possible angina (yes/no) | 1.97 | 1.21 to 3.22 | 0.0068 |

| Possible angina (yes/no) | 1.79 | 1.26 to 2.10 | 0.0220 |
| Age (1 SD = 5.46 years) | 1.31 | 1.14 to 1.51 | 0.0002 |
| Smoking (yes/no) | 1.63 | 1.26 to 2.10 | 0.0002 |
| Cholesterol (1 SD = 1.19 mmol/l) | 1.20 | 1.07 to 1.34 | 0.0015 |
| SBP (1 SD = 17.59 mm Hg) | 1.26 | 1.13 to 1.42 | <0.0001 |
| MHR (1 SD = 13.3 beats/min) | 0.79 | 0.69 to 0.90 | 0.0004 |
| Physical fitness (1 SD = 0.785 J/kg) | 0.83 | 0.70 to 0.99 | 0.0360 |

Data are given for eight variables collected during the baseline examination, including possible angina.
CI, confidence interval; FEV1, forced expiratory volume in one second; MHR, maximum heart rate on exercise; RR, relative risk; SBP, systolic blood pressure.
