Serum Markers in Rheumatoid Arthritis: A Longitudinal Study of Patients Undergoing Infliximab Treatment

Figure 4

Matrix metalloprotease levels in serum from the RA patient cohort. (a) to (e) are scatter dot plots, where each dot represents one individual patient. The -axes illustrate the four assessment months after infliximab treatment is initiated. The -axes represent the concentrations in serum of their respective MMP in picograms per millilitre (pg/mL) on a scale. The horizontal lines in the dot plot illustrate the mean, and the vertical error lines represent ± standard error mean (SEM) in a paired -test.
