Comparison of event-based analysis Kaplan-Meier curves of three-dimensional minimum distance band (MDB) thickness measurement across global overall, inferior, and superior quadrants methods. Log-rank tests were used to compare the global MDB thickness method to the inferior quadrant and superior quadrant methods, with P = 0.67 and P = 0.33 respectively. Additionally, for the comparison between the inferior quadrant and superior quadrant, P = 0.48, indicating that there is no significant difference among the three methods in detecting glaucoma progression using event-based criterion. The Holm method was used to adjust the log-rank tests for multiple comparisons.
