Concentrations of VEGF-A and TGF-β isoforms in the rabbit aqueous humour. Each point represents the concentration in one eye. Where there were less than 6 data points, the absent values were beyond the threshold of detection assigned by the assay. The mean concentration ± SD for each treatment and time point is shown. Cytokine concentrations in aqueous humor collected on day 0 via ACP are considered preoperative baseline values for statistical comparison. *, P < 0.05 (Bonferroni-adjusted) relative to the respective baseline value on day 0. A, ACP only in left eye (n = 6); P, ACP with PI in contralateral eye (n = 6)
