Figure 3. A developed stroke nomogram in the primary cohort (N = 1,354). Abbreviations: SBP: systolic blood pressure; CHD: coronary heart disease; AF: atrial fibrillation; CRP: C-reactive protein; ESR: erythrocyte sedimentation rate; TC: total cholesterol; LDL: low-density lipoprotein. For example, a 70-year-old (47 points), male (30 points) RA patient with an AF (55 points) and CHD (62 points) history of 60 mm/H ESR (27 points), and 5 mmol/L TC (65 points) arrived at a total point value of 286, with a probability of 46% of developing a stroke.
