Odds ratios (ORs) adjusted for diagnostic status (cancer /OED), age (≤50, 51–60, 61–70, 71+), working outside the home, social support (BSNI, >low vs. low), and sex as well as either level of alcohol consumption in quartiles (< 1.5, 1.5–<8, 8–<23, 23+ drinks/week) or diagnosis-year smoking. All adjusted ORs exclude 3 subjects who did not answer BSNI questions.
