Mean Absolute Difference in Amplitude Between A-Scan Profiles Using Amplitude Normalization as the Next Step Following Z-Scaling and Sampling Density Normalization

	Overall (%)	Temporal (%)	Superior (%)	Nasal (%)	Inferior (%)
Baseline residual	12.7	12.8	12.4	13.0	12.6
First percentile	20.5 (7.8)	20.8 (8.0)	20.2 (7.9)	20.8 (7.8)	20.0 (7.4)
33rd percentile	12.6 (−0.0)	12.6 (−0.1)	12.4 (0.0)	12.9 (−0.1)	12.5 (−0.1)
50th percentile	10.7 (−2.0)	10.6 (−2.2)	10.5 (−1.9)	11.0 (−2.0)	10.6 (−2.0)
66th percentile	8.7 (−4.0)	8.6 (−4.2)	8.5 (−3.9)	9.1 (−3.9)	8.6 (−4.0)
Data range matching	19.6 (6.9)	20.3 (7.5)	18.9 (6.5)	19.8 (6.8)	19.4 (6.8)

Absolute difference is in percentage with the difference of baseline residual from the residual after amplitude normalization in parentheses.
