| Variable | Parameter Estimate | p-value | 95% CI | |
|---|---|---|---|---|
| (Intercept) | α | 68.705 | <0.001 | (65.47, 71.94) |
| BMI -25* | β1 | -0.687 | 0.02 | (-1.24, -0.13) |
| Current smoking (yes) | β2 | -5.51 | 0.06 | (-11.32, 0.303) |
| Age -50* | β3 | -0.423 | <0.001 | (-0.665, -0.180) |
CI, confidence interval; BMI, body mass index.
R2 = 0.13.
