Relationship between age and subfoveal choroidal thickness. Age is not related to choroidal thickness in simple linear regression (p = 0.688, y = -0.188x + 279.35, R2 = 0.003). Age is negatively correlated with choroidal thickness in multiple linear regression (p = 0.015, y = 341.584 - 1.306x1 + 13.621x2, R2 = 0.202).
