Fig. 1: Interleukin (IL)-6 concentrations measured in aqueous humour and serum samples collected at month 2 of HARBOR.

Box and whisker and scatter plots (a) and individual patient-level (b) interleukin (IL)-6 concentrations. In the box and whisker plot, the top and bottom lines of the box indicate the first and third quartiles, the centre line in the box indicates the median, the ends of the lines indicate the maxima and minima and the diamond indicates the mean. Pearson correlation coefficient: −0.1696. *Derived from Wilcoxon rank sum test comparing median aqueous humour and serum IL 6 concentrations.
