  • Bold: 95% CI does not include 1.00.

  • SIRs are adjusted for sex (not sex-specific SIRs), age, time period, geographic region of residence and educational level. SIRs for males are calculated only for males with and without a family history, and SIRs for females are calculated only for females with and without a family history.

  • COPD, chronic obstructive pulmonary disease; O, observed number of cases; SIR, standardised incidence ratio.
