HR With 95% CI for the Association Between HADS‐D (Continuous, 3 Categories, Combined Values from HUNT2 and HUNT3), and Risk of AAAa

Number of individuals (continuous vs 3 categories), n=50 657. Number of individuals (combined categories), n=20 366. AAA, abdominal aortic aneurysm; HADS‐D, Hospital Anxiety and Depression Scale–Depression; HR, hazard ratios; HUNT, Norwegian Nord‐Trøndelag Health Study.
HR estimates with 95% CIs calculated in a Cox proportional hazard regression model with attained age as time scale.
HR estimates with 95% CI for all 3 HADS‐D variables (continuous vs 3 categories, combined categories) in separate models, but equally adjusted for age at HADS‐D measure (HUNT participation), sex, diabetes mellitus, body mass index, coronary heart disease, hypertension, total cholesterol, and smoking.
Combined categories of HADS‐D were defined as, never (<8, <8), intermittent (<8,≥8 or ≥8,<8), persistent (≥8, ≥8).
