CXCL9 and dry age related macular degeneration: The concentrations of three cytokines were 1.7 to 72.8-fold higher (p<0.0012) in patients with either dry AMD [CXCL6 (p = 0.00067)] and/or treated wet AMD [CXCL5 (p = 0.00099), CXCL6 (p = 0.00067), MIG/CXCL9 (p = 0.00019)] than in the healthy controls, with significant intergroup differences being registered after the application of the Bonferroni correction (Fig 2, Table 3).
