Figure 2. Linear Spline Mixed-Effect Models of Retina Layer Thicknesses.

Linear spline mixed-effect models with 2 knots at 26 and 71 days for the GCIPL (A) and pRNFL (B). The black points joined by a dashed line represent the individual trajectories of retinal thickness changes, the thicker curves represent the individual fit of the model, and the dark red line represents the population model.
