Distribution of pulmonary function risk factors and pulmonary function (ml) according to level of hostility at baseline
| Risk factor | High hostility(n = 214) | Medium/low hostility(n = 455) |
|---|---|---|
| Tests of significance were conducted using χ2, t tests, or analysis of covariance, controlling for age and height (FEV1, FVC). | ||

| Height (inches) | 68.7 | 68.5 |
| Current smokers (%) | 16% | 11% |
| Former smokers (%) | 57% | 51% |
| Education beyond high school (%) | 89% | 91% |
