Estimates from multiple linear regression models for age, adjusting for patient race, sex, tumour location and grade among patients with stage I or II disease (first column) and stage I, II or III disease (second column)
| Stages I, II | Stages I, II, III | |
|---|---|---|
| Adjusted mean age (years), T1 | 60.03 (58.56 to 61.5) | 60.68 (59.3 to 62.06) |
| Age difference (years): T2 vs T1 | −0.01 (−1.06 to 1.05), p=0.99 | 0.03 (−1.03 to 1.1), p=0.95 |
| Age difference (years): T3 vs T1 | 0.95 (0.01 to 1.89), p=0.05 | 1.06 (0.11 to 2), p=0.03 |
| Age difference (years): T4 vs T1 | N.A. | 1.19 (0.11 to 2.27), p=0.03 |
Separate models were estimated for varying subgroups of patient stage of disease. Values given are mean differences in ages by T stage, with 95% CIs.
