Multiple Linear Regression Results Predicting Perceived Difference in Life Expectancy with Treatment Choice (n = 235)
| Variable | b (95% CI) | SE | β | P value |
|---|---|---|---|---|
| Age | −0.18 (−0.31 to −0.04) | 0.07 | −0.18 | .01 |
| Race (Black = 0, White = 1) | −1.32 (−3.24 to 0.61) | 0.98 | −0.09 | .18 |
| General health perception | 1.20 (0.08 to 2.33) | 0.57 | 0.14 | .04 |
| Perceived cancer seriousness | 0.97 (0.21 to 1.73) | 0.39 | 0.17 | .01 |
| Cancer risk levela | −0.39 (−1.87 to 1.08) | 0.75 | −0.04 | .60 |
| Surgery vs WW/AS | 3.77 (0.50 to 7.04) | 1.67 | 0.25 | .02 |
| Radiation vs WW/AS | 4.06 (0.87 to 7.25) | 1.62 | 0.25 | .01 |
WW/AS = watchful waiting or active surveillance; b = Unstandardized regression coefficient; β = Standardized regression coefficient.
