Table 3.
Regression analyses of VFDR against significant variables from univariate analyses. Model 1 contains the treatment arm indicator variable alone. Model 2 contains the treatment arm indicator variable and age of diagnosis. a The estimated mean difference in VFDR for ATL vs. SRS. b The estimated mean difference in VFDR corresponding to 1 year increase of age diagnosis.
| Model | Regression coefficient | 95% confidence limits | P | |
|---|---|---|---|---|
| 1. Arm (ATL vs. SRS) | −0.033a | −0.146 – 0.79 | 0.079 | |
| 2. Arm (ATL vs. SRS) | −0.061a | −0.171 – 0.049 | 0.269 | |
| Age diagnosis (years) | −0.005b | −0.009 - −0.001 | 0.016 |
