Some variables in the multivariable model are not listed here owing to table length, namely, geographic region, educational level, multiple comorbidities (hypertension, stroke, arthritis, psychiatric illness, and type 1 or 2 diabetes), and smoking status. No differences were seen in these variables between participants with and without cancer.
Data are presented as number (percentage) of participants unless otherwise indicated.
