This table shows the performance of OKULIX and ML-based approaches for patients in the short, medium and long axial length group. The per cent improvement was calculated as . The Wilcoxon test was performed to compare the difference in the absolute errors between OKULIX and ML-based approaches in three different axial length groups.
AL, axial length; MAE, mean absolute error; MedAE, median absolute error; ML, machine learning.
