SOURCE Authors’ analysis.
NOTES Hazard rates were calculated using Cox proportional hazards regression models and were significantly different from 1 (p = 0.05) except in the following cases: leukemia or lymphoma (leuk/lymph), lung, and melanoma for nonmarried versus married people; and melanoma and uterine for group-law interaction. People in the group without cancer were matched to cancer patients by age, sex, and ZIP code of residence. The individual cancer types listed are those with the highest cumulative incidence of bankruptcy among all cancer types examined from the National Cancer Institute’s Surveillance Epidemiology and End Results Program (SEER).
Reference is no cancer.
Reference is before October 17, 2005, when the Bankruptcy Abuse Prevention and Consumer Protection Act of 2005 went into effect.
Reference is married. Nonmarried is single, divorced, widowed, or marital status unknown.
Reference is cancer. This accounts for the differential impact of the Bankruptcy Abuse Prevention and Consumer Protection Act of 2005 on those with cancer versus those without cancer.
