  1. CRP quartile categories at baseline were as follows: < 0.54, 0.54–0.98, 0.99–1.92, 1.93–10.00 mg/L; WBC quartile categories at baseline were as follows: 4.0–5.0, 5.1–5.9, 6.0–7.0, 7.1–10.0 109/L.
  2. Q1 as the lowest quartile and Q4 as the highest quartile. CRP and WBC as continuous variables were log transformed
  3. β (95% CIs) was calculated by linear mixed-effect models and presented as multiply by 102
  4. Model1: adjusted for age, sex, education level, marital status, smoking status, drinking status, residence, and body mass index; Model 2: additionally adjusted for frailty index at baseline
  5. CRP C-reactive protein, WBC white blood cell
