Struglics Osteoarthritis and Cartilage Volume 23, Issue 9, Pages 1506-1512 (September 2015) DOI: 10.1016/j.joca.2015.04.022 Copyright © 2015 Osteoarthritis Research Society International Terms and Conditions

Fig. 1 Synovial fluid C2C concentrations after knee injury. Samples were ordered by time after injury and divided into groups of 30–47 subjects each according to Table I, with day 0 plotted at 0.33 days (8 h) due to the logarithmic X-axis. The results are expressed as means with 95% confidence intervals compared with concentrations in the reference group (dotted line and gray area). SF, synovial fluid.

Fig. 2 A bivariate scatter plot of C2C concentrations in synovial fluid (SF) and serum from knee injured patients. All 71 subjects with available data (circles) are plotted. A regression line (solid), and a line of equality (dashed) are indicated.
