Incidence densities per 1000 person years for atrial fibrillation according to 1 μg/L interval categories, with open-ended extreme categories, of Plasma Procollagen Type III N-Terminal Propeptide (PIIINP, A) and Plasma Collagen Type I CarboxyTerminal Telopeptide (ICTP, B).
Blue line: adjusted for demographics (age, race/ethnicity, and sex)
Red line: adjusted for demographics and for systolic blood pressure (SBP), height (Ht), body mass index (BMI), current smoker, and estimated glomerular filtration rate (eGFR)<60 ml/min/1.73 m2. Covariates are set to their overall means in the plotted points.
Further adjustment for heart rate, diastolic blood pressure, blood pressure lowering medications, former smoking, diabetes, total cholesterol, HDL-cholesterol, triglycerides, cholesterol-lowering medication, hsCRP, IL6, D-dimer, GlycA, and small plus medium HDL particles), did not substantially alter the estimates and is not shown.
