Correlations between the levels of TNFα in culture supernatants and the numbers of CD34⁺ cell subpopulations and clonogenic progenitor cells.

Diagrams show linear regression analysis for the correlation between the values of TNFα in LTBMC supernatants and the proportion of CD34⁺ cells (A), the number of CFCs (B), the percentages of CD34⁺/Fas⁺ cells (C), and the proportion of CD34⁺/7AAD^dim cells (D) in the entire group of subjects (26 patients with RA and 11 healthy controls). Coefficient of correlation (r) and degree of significance (P) are indicated. Regression lines are shown as solid lines and the 95% confidence limits as dotted lines. Patients with RA, (●); healthy controls, (○).
