only marginally significantp value < 0.05
In the 48 eyes, all but 1 of the 9 zones, there was a small mean thinning over the study period, though standard deviations (SDs) were extremely large such that thinning was only marginally significant in 3/9 zones ( p value < 0.05) and highly significant in 1/9 zones ( p value = 0.002).
