Plasma and urinary monocyte chemoattractant protein-1 (MCP-1). Log-transformed plasma (a) and urinary (b) MCP-1 levels among nondiabetic subjects, diabetic patients with no known kidney disease (diabetic), and patients with diagnosed diabetic kidney disease (DKD). Urinary MCP-1 levels were normalized to creatinine to account for differences in urine concentration. Data are represented as both a bar chart showing mean -1 ± SEM within each group (top) and a scatter plot showing values for each individual within the group (bottom). Labeled means without a common letter are significantly different from one another based on one-way ANOVA and Tukey’s honest significant difference test.
