Model 1 was adjusted for age at risk, sex, and their interaction. Model 2 was also adjusted for disposable income and population density. A likelihood ratio test confirmed statistical interaction between sex and age at risk in model 1 (χ2 (df=4) 71.5; P<0.001) and model 2 (χ2 (df=4) 73.0; P<0.001), as well as between sex and refugee status in model 1 (χ2 (df=2) 11.7; P=0.003) and model 2 (χ2 (df=2) 13.5; P=0.001). Hazard ratios by refugee status are therefore presented separately for men and women.
