CD14⁺ cells in peripheral blood. PBMCs from patients with active or non-active RA or healthy controls were collected at baseline. 1a: CD14⁺cells: From PBMCs, CD14⁺ mononuclear cells were counted using standard flow cytology. Results are expressed as the number of CD14⁺ cells/10000 cells (mean ± SD). All graphs are presented as Box-and-Whisker Plots [median, IQR (25–75)]. *p < 0.05, ***p < 0.001 (comparisons as indicated). 1b: Correlation analysis: Correlation between RA activity (DAS 28) and the number of CD14⁺ cells/10000 cells was presented graphically (95% confident bands of the best fit diagonal line are shown).
