Multiple regression model of p16INK4a expression and covariates.
| Variable* | Label | Parameter estimate ±SE** | p-value |
|---|---|---|---|
| Age | Per chronological year | 0.04±0.005 | <.0001 |
| Pack-yrs | 0: Pack-yrs <= 5, 1: Pack-yrs > 5 | 0.36±0.17 | 0.0348 |
| Exercise | 0: min/month <= 240, 1: min/month > 240 | -0.61±0.15 | 0.0001 |
Estimated intercept: 4.21
Parameter estimate indicates change in Log2-transformed p16INK4a expression per unit change of covariant. SE: standard error
