Associations of the eight selected biomarkers, categorized as quartiles, with poor self-rated health. Odds ratios (ORs) and 95% confidence intervals (CIs) are from the logistic regression models, adjusted for age and gender. The “best” biomarker quartile was used as reference category. (A–H): C-reactive protein (CRP), high-density lipoprotein (HDL) cholesterol, haemoglobin A1C (HBA1C), 25-hydroxyl-vitamin-D (25-OH-vitaminD), zeaxanthin, apolipoprotein-B (Apo-B), cell-free DNA (cf-DNA) and protein carbonyls, respectively. The biomarkers were selected as examples of replicated and new associations representing different biological domains.
