Association of socioeconomic deprivation and observed survival and adjusted 5-year survival estimates for each single registry using deprivation quintiles derived within the catchment area of the registry.
| Cancer registry | Deprivation quintile [Hazard ration (95% confidence interval)]a | 5-year survival (standard error)c | |||||||
|---|---|---|---|---|---|---|---|---|---|
| Q1(least deprived) | Q2 | Q3 | Q4 | Q5(most deprived) | Cityb | Q1 (%) | Q5 (%) | Q5–Q1 (% units) | |
| Dresden | 1.00 (ref) | 1.07 (0.95–1.21) | 1.00 (0.89–1.12) | 1.10 (0.99–1.23) | 1.18 (1.06–1.32) | 0.82 (0.75–0.90) | 51.5 | 47.2 | −4.3 |
| Erfurt | 1.00 (ref) | 0.94 (0.81–1.08) | 0.92 (0.81–1.05) | 1.02 (0.89–1.17) | 0.99 (0.86–1.14) | 1.01 (0.89–1.13) | 47.9 | 48.1 | 0.2 |
| Regensburg | 1.00 (ref) | 0.99 (0.93–1.06) | 1.01 (0.95–1.08) | 0.99 (0.92–1.06) | 1.04 (0.98–1.11) | NA | 51.8 | 50.7 | −1.1 |
Ref, Reference; Q, quintile; NA, not applicable as the city Regensburg was included in the quintiles; Significant hazard ratios (p < 0.05) are printed in bold.
adjusted for age, sex, period, cancer site, cancer grade, cancer stage, and surgery.
for the cancer registries Dresden and Erfurt, the cities Dresden and Erfurt were classified separately, as they would otherwise dominate the classification of the quintiles. The deprivation value for Dresden lies between Q1 and Q2 in 2006 and in Q2 in 2010. For Erfurt, it lies in Q1 in 2006 and in Q2 in 2010.
five-year overall survival derived from the direct adjusted survival curves from the adjusted Cox proportional hazard regression model.
