Figure 2: The predicted tumor thickness over time for uveal melanomas with tumor thickness that developed systemic metastasis (dark gray line) versus those that did not develop systemic metastasis (black line). Note, the predicted thickness is plotted for the average initial tumor thickness category, 3-8 mm. (a) initial tumor thickness <3 mm, (b) initial tumor thickness 3-8 mm, (c) initial tumor thickness >8 mm
