Crude model with race as only predictor for time to surgery
Full model with race as main predictor for time to surgery with confounders: age, marital status, urban status, cancer grade, distance, BCN enrollment, hormone receptor status, county and insurance provider.
Final model with race as main predictor for time to surgery with select confounders based on backward selection in SAS: marital status, distance, BCN enrollment and insurance provider.
For stratification by insurance status, full model had race as main predictor for time to surgery with confounders: age, marital status, urban status, cancer grade, distance, BCN enrollment, hormone receptor status and county; while final model had race as main predictor for time to surgery with select confounders based on backward selection in SAS: marital status, distance and BCN enrollment.
