Effects of ACL Reconstructive Surgery on Temporal Variations of Cytokine Levels in Synovial Fluid

Figure 2

Time-related modifications of cytokine levels compared to chronic ACL group. Cytokine concentrations measured at different time points in the longitudinal group () are represented in the box-plot. In each box-plot, the box is built within the third (upper bound) and first (lower bound) quartiles (i.e., ,  ); the middle line represents the median. Whiskers represent data maximum (upper whisker) and minimum (lower whisker). + indicates data outliers, defined as data points below or above . Grey shaded area represents the interquartile range of the chronic ACL tear group ().
