: Represent the crude odds ratios
: Odds ratios were adjusted by age at diagnosis (<30, 30–39, 40–49, 50–59, 60–69, ≥70), gender (male/female), BMIs (<18.5, 18.5–23.9, 24.0–27.9, ≥28.0), family history of diabetes (yes or no), physical exercise (no, occasionally, often), smoking index, (no smoking, 0–6.3, 6.4–14.0, 14.1–23.2, ≥23.3), lifetime total alcohol intake, (no drinking, 0–72.2, 72.3–167.5, 167.5–380.1, ≥380.1), triglyceride (<1.70 mmol/L, 1.70~2.25 mmol/L, >2.20 mmol/L), high-density lipoprotein (<1.04 mmol/L, 1.04–1.55 mmol/L, >1.55 mmol/L), low-density lipoprotein (<2.60 mmol/L, 2.60–4.11 mmol/L, >4.12 mmol/L).
: Odds ratios in model 2 were further adjusted by serum level (μg/L) of Nickel, Cobalt, Copper, Zinc, Cadmium, Mercury, Chromium, Arsenic, and Magnesium (continues variables) on the basis of adjusted confounding factors in model 1.
