Figure 1.

The distribution of the individual vitreous concentrations of (A) HTRA1, (B) TGF-${\mathsf{\beta }}_2$, (C) TGF-${\mathsf{\beta }}_3$, and (D) VEGF by group. Note that HTRA1 levels were measured as ${10}^{-9}$ mol/L, and TGF-${\mathsf{\beta }}_2$, TGF-${\mathsf{\beta }}_3$, and VEGF were measured as pg/mL. p-values are indicated in the plots, * p < 0.05.
