n, number of events.
Adjustment included age (restricted quadratic spline with knots at the 10th, 50th, and 90th percentile of the overall study sample), race/ethnicity (non-Hispanic white, non-Hispanic black, Mexican American, other), postmenopausal status (among women), urban residence (urban, rural), annual household income (< $20,000, ≥ $20,000), high school education, smoking category (never, former who quit ≥ 4 years ago, former who quit < 4 years ago, current), tertile of pack-years (< 9.0, 9.0–28.2, ≥ 28.2), physical activity (none, 1–2, ≥ 3 times a week), diabetes, BMI (continuous), alcohol consumption (< 12, ≥ 12 drinks in the past year), CRP (not detectable, 0.3–0.9, ≥ 1.0 mg/dL), total cholesterol (continuous), systolic blood pressure (continuous), blood pressure–lowering medication, blood lead (log-transformed), and eGFR (< 60, 60–89, ≥ 90 mL/min, 1.73 m2).
Because of few cancer (n = 15 for men and women) and coronary heart disease (n = 21 for men and n = 19 for women) deaths in the lowest tertile, the hazard ratio estimates for cancer and coronary heart disease mortality may be unstable.
