Table 2.
Models for all-cause survival and breast cancer specific survival fitted with and without inclusion of ZCTA SES data. All models were adjusted for patient race, age, and stage. Models 1.1a, 1.2a, 1.3a, 1.4a controlled for ZCTA poverty level. Bolded indicates significance at 95% confidence (p < 0.05).
Model 1.1a: Isolation & Poverty | Model 1.1b: Isolation only | Model 1.2a: Exposure & Poverty | Model 1.2b: Exposure only | Model 1.3a: Full LEx/Is & Poverty | Model 1.3b: Full LEx/Is only | Model 1.4a: LQ & Poverty | Model 1.4b: LQ only | Model 1.5a: ICE with Race & Income | Model 1.5b: ICE with Race (No Income) | |

Note: segregation hazard ratio magnitude cannot be directly compared across models with different metrics, due to differences in unit definition.
