Fig. 4

This forest plot summarizes the results of five studies evaluating the correlation between temporal para-foveal retinal thickness and superficial capillary plexus (SCP) density, expressed as Fisher’s z-transformed correlation coefficients. Each study is represented by a square (point estimate), with horizontal lines denoting 95% confidence intervals. The size of each square reflects the study’s weight in the meta-analysis. The overall pooled effect, calculated using a random-effects (RE) model, is shown as a diamond at the bottom of the plot. A significant positive correlation was found, with a pooled Fisher’s z value of 0.70 [95% CI: 0.51, 0.89], indicating that greater para-foveal thickness is associated with increased SCP density.
