Regression graphs of the relationship between serum levels of MCP-1 relative to age of subjects (a, b & c) and duration of T1D (d, e & f).

<p>a) Relative levels of MCP-1 as a function of Age in females (β = −0.005, R = −0.06) and males (β = −0.0013, R = −0.02) in the control group. b) Relative expression of MCP-1 in serum of T1D females (β = 0.005, R = 0.11) and males (β = 0.002, R = 0.04). c) Mean serum MCP-1 levels (regression lines) according to age. d) Regression for duration of disease for female patients (β = 0.009, R = 0.14). e) Regression for duration of disease for male patients (β = 0.005, R = 0.08). f) Mean serum MCP-1 levels (regression lines) according to duration of T1D. β: slope of regression, R: correlation coefficient.
