Figure 4

Boxplot shows mean ganglion cell + inner plexiform layer (GC + IPL) thickness of each study group with macular cube 200×200. Mean CGL + IPL and mean RNFL were thinner in the group with DM with no DR when compared to control (P < 0.05). ANOVA with Bonferroni post test indicated a statistically significant reduction in GCL + IPL in DM with no DR compared to control (P = 0.039).
