CI = confidence intervals

HRT = Heidelberg retina tomograph

MRA = Moorfields regression analysis

ONL = outside normal limits

PSD = pattern standard deviation.

Number of eyes (%) – P value based on chi-square.

^†

Mean (95% CI) – P value based on t test.

^‡

Median (Q1–Q3) – P value based on Wilcoxon test.
