  • *The ranges of each quartile for weight were 30-57, 58-63, 64-69, and 70-115 kg for men, and 27-49, 50-53, 54-59, and 60-98 kg for women.

  • HRs were adjusted for age at baseline (continuous), gender (men or women), study area (10 public health center areas), number of pack-years (0, 1-19, 20-29, 30-39, and ≥40 pack-years, as an ordinal variable), alcohol category at baseline (nondrinkers, occasional drinkers, and 1-149, 150-299, and ≥300 g/wk, as an ordinal variable), and height category at baseline (four quartiles).
